Although Supergirl hasn’t been established as part of The CW’s DC Comics shared television universe – which includes Arrow, The Flash, and the recently premiered Legends of Tomorrow – questions of a crossover began to be raised almost immediately after the CBS superhero drama was announced. With Greg Berlanti acting as executive producer and co-creator on Supergirl, and since he was instrumental to constructing The CW’s DC universe, it seemed to be only a matter of time before Supergirl would crossover with The Flash, Arrow, and/or Legends of Tomorrow – though Supergirl executive producer Ali Adler said it was important that the show stand on its own first and foremost.

More recently, talk of crossovers came up again at the Television Critics Association 2016 Winter Press Tour, with Berlanti and CW boss Mark Pedowitz talking about being open to a crossover, then CBS president Glenn Geller further teasing the possibility. Now, we have official confirmation that Central City’s CSI tech Barry Allen a.k.a. The Flash (Grant Gustin) will be paying a visit to Cat Grant’s assistant Kara Danvers a.k.a. Supergirl (Melissa Benoist) in the upcoming March 28th episode of Supergirl, titled ‘Worlds Finest’.

Aside from the date and episode title, though, little is known about the episode at this point, including how the show will explain The Flash’s existence in National City – whether The Flash and Supergirl always existed in the same world, or if Barry travels to a different Earth by way of the Multiverse. But, while this crossover may be a good time to establish how Supergirl connects to The CW’s DC Comics universe, it could also be the perfect opportunity to give the fans something else they want: a musical episode. So, here’s why a Supergirl and The Flash crossover musical could work.

Musically-Talented Superheroes

The cast certainly has the chops; both Gustin and Benoist appeared on Fox’s musical dramedy series, Glee. Plus, fellow Supergirl cast members Jeremy Jordan, who plays Kara’s co-worker Winn Schott, and Laura Benanti, who portrays the identical twin sisters Kara’s mother and aunt Astra, are accomplished stage performers. Jordan starred in The Last Five Years, joined the NBC musical series Smash in its second season, and appeared on broadway in musicals like Newsies, Bonnie & Clyde, and Rock of Ages. Benanti, for her part, is a Tony-award winning actress for her role in the 2008 revival of Gypsy, and she has additionally appeared in ABC’s country music series Nashville (as well as NBC’s The Sound of Music Live!).

Because of all the musical talent at the heart of Supergirl, whether audiences would see the stars put those sets of abilities to use on the CBS superhero drama became a popular question for the cast prior to the show’s premiere and in its early months. Jordan, for instance, told Zap2it that his goal in landing the role on Supergirl was to play a part that didn’t depend on his musical talents. Although, he also said he “wouldn’t be opposed to [singing] if they asked me, but I’m certainly not expecting anything like that. And I’m not pushing for it, either.”

Additionally, during an interview with in which he also spoke about Winn’s role as Kara’s “fanboy” early in Supergirl season 1, Jordan was asked about the potential of a musical episode:

“You know, that’s up to the producers. I think if that happens, wait a second, let us establish these new characters, because people see especially Melissa and I as singers, ahead of being just an actor. I think it would be cool to do that down the line, though.”

Benanti also commented to The Wrap soon after the show premiered on the possibility of Supergirl’s musically apt cast members contributing to a musical episode:

“We’ve been joking about it. Maybe we’ll do an online one! We’ve been talking about it. Melissa is pretty busy right now. She’s got a lot on her plate, but if she gets some downtime, that’s definitely something we’ve been talking about.”

So, when Supergirl first premiered it seemed like a long shot that the writers and producers would be doing a musical episode in the show’s first season, but it was something that was on the cast members’ minds – whether because they were asked about it so much or because it came up naturally between the musically inclined cast mates. However, now that Gustin has been added to the mix for the March crossover, the call for a musical episode – or, at the very least, a musical component to the episode – has seen a resurgence, prompting an article on The Daily Dot, and generated talk among fans on Twitter.

The Flash already gave fans a nod to its star’s musical talent in the season 1 episode ‘Crazy For You’, and officially established that Barry Allen can perform “Summer Nights” flawlessly at karaoke. Additionally, Supergirl has established that its younger characters – Kara, Winn, James Olsen (Mechad Brooks), and Lucy Lane (Jenna Dewan-Tatum) – partake in a regular game night. So, when the story makes sense, both shows have portrayed its lead characters having fun doing everyday activities of non-superhuman twenty-somethings, which can include singing and/or dancing.

Additionally, Supergirl and The Flash share a much lighter, and at times sillier, tone than fellow DC Comics television shows Arrow (as well as what we’ve seen so far of Legends of Tomorrow). These tones are established by the shows’ shared creative teams that include Berlanti and Flash showrunner Andrew Kreisberg, while series’ leads, Benoist and Gustin, carry the lighter tone off exceptionally well – perhaps due to their past work on Glee, which also featured a balance of sometimes-serious, sometimes-silly story content.

A Musical Super-Villain

The Flash Supergirl Musical Crossover Music Meister Why Supergirl & The Flash Should Have a Musical Crossover

The biggest question of whether Supergirl and The Flash could pull of a musical episode is how the show would establish the reasoning behind the characters breaking out into song and dance. The impetus of a DC Comics musical episode can be found on DC Comics’ animated series Batman: The Brave and the Bold. The episode ‘Mayhem of the Music Meister!’ introduced DC villain Music Meister (voiced by Neil Patrick Harris), who can use his singing voice to hypnotize and control the minds of those within hearing range. Specifically, he can force his victims to express themselves through song and dance – just like they would in a musical. Music Meister resembles the musical demon, Sweet (Hinton Battle), who was the force behind Buffy the Vampire Slayer’s fan-favorite season 6 musical episode ‘Once More, with Feeling’.

So, the DC Comics mythology has the perfect villain to incite a musical episode (though Music Meister doesn’t present an obvious reasoning for Supergirl needing The Flash’s help). Plus, Music Meister isn’t too different from the other less well known villains to be adapted to both Supergirl and The Flash. In its two seasons, The Flash has featured a number of campy villains like Captain Cold and the Trickster. A campy one-off villain also wouldn’t feel too out of place on Supergirl, whose hero recently faced off against Toyman. Given the sillier leanings of storylines featuring the Trickster and Toyman especially, Music Meister doesn’t seem like too far of a stretch for a Supergirl crossover with The Flash. Perhaps Harris would even be willing to reprise his role as Music Meister.

In terms of casting, neither Supergirl nor The Flash are above making decisions that also give a nod to DC Comics fans. The Flash cast former 1990s Barry Allen John Wesley Shipp as Henry Allen, the father of Gustin’s take on Barry. Plus, Mark Hamill played the Trickster both on The Flash of the early ’90s and the current incarnation. As for Supergirl, the show recently announced that Laura Vandervoort, who previously portrayed Superman’s heroic cousin on Smallville, will appear in an upcoming episode as DC Comics’ Indigo. If Supergirl were to use Music Meister, the Berlanti team could certainly have some fun with casting.

So, although it’s far from confirmed, a musical episode or a musical aspect to the crossover episode between Supergirl and The Flash could be a fun way to bring these characters together for a lighter storyline that manages to utilize the abilities of not only the leads, but certain supporting cast members as well. Whether Supergirl uses Music Meister as a way to introduce a musical element to the episode, or a more everyday means like karaoke, it would provide an added level of enjoyment for fans as well as finally appease those who have been clamoring for a musical episode – which has almost been as long as fans have been asking for a crossover.

Certainly, there will be those that would prefer Supergirl stay away from musical numbers and dance routines (and Jordan himself may very well be included in that group) in order to simply focus on the fact that these newest incarnations of Barry Allen and Kara Danvers will appear together on a television series for the first time. But a musical episode would fit right in with the tone of Supergirl and The Flash, and would be a fun way to make this crossover even more special, both for the stars and the fans.

Supergirl will return with “For The Girl Who Has Everything” next Monday on CBS @8pm. The Flash will return with “Welcome to Earth-2″ next Tuesday on The CW @8pm. Arrow and DC’s Legends of Tomorrow air during the same time-slot on The CW on Wednesdays and Thursday, respectively.
