Fans of The CW have shipped Barry Allen and Kara Danvers ever since the two heroes first flirted with one another in their crossover last year. While both of these characters are now romantically involved with other partners, we're still thrilled to see The Flash and Supergirl make sweet music together when the musical crossover airs later this month.

In recent weeks, we've learned more and more about what this crossover will entail, including some information on Supergirl's new costume and who will play the villainous Music Meister. Now, we've finally been given our first glimpse of our heroes in action thanks to this new trailer from :

While that first clip flew by faster than Supergirl on speed, The CW have kindly provided us with a second, longer promo that delves into the story line itself and gives us a brief taste of the dance numbers.

Although things will kick off on Kara's Earth when the Music Meister whammies into a coma, the musical itself will take place on , where Mon-El and Hank Henshaw recruit the help of Team Flash.

Here's the full official synopsis for 'Duet':

“Barry (Grant Gustin) and team are surprised when Mon-El (guest star Chris Wood) and Hank Henshaw (guest star David Harewood) arrive on their Earth carrying a comatose Supergirl (guest star Melissa Benoist) who was whammied by the Music Meister (guest star Darren Criss). Unable to wake her up, they turn to Team Flash to save her. However, the Music Meister surprises The Flash and puts him in a similar coma, one that Team Flash can’t cure. Kara and Barry wake up without their powers in an alternate reality where life is like a musical and the only way to escape is by following the script, complete with singing and dancing, to the end.”

The teaser trailer provides us with a glimpse of the '40s style world that our heroes are forced to navigate together, singing and dancing their way through the Music Meister's fantasy realm. While we're yet to hear Supergirl or The Flash test out their pipes together in the promos, their previous stints on Ryan Murphy's prove that they're more than capable of saving the day through song.

Reports also confirm that Melissa Benoist and Grant Gustin will share the mic with fellow Arrowverse cast members such as Jesse L. Martin (Detective Joe West), Carlos Valdes (Cisco Ramon/Vibe), Jeremy Jordan (Winn Schott), John Barrowman (Malcolm Merlyn) and Victor Garber (Martin Stein). Presumably, alumni will join the fun as fantasy figures within The Flash and Supergirl's shared coma, rather than as part of an actual visit from the Waverider's crew.

Together, the Arrowverse warblers will sing a variety of songs, some of which are yet to be confirmed. So far though, we know that fellow CW star Rachel Bloom () has penned a duet between the two leads adorably called 'Super Friends'. will also perform a solo number called 'Runnin’ Home to You,' which was composed by the Oscar-winning duo Benj Pasek and Justin Paul, who recently penned the already iconic song 'City of Stars' from La La Land.

As if that wasn't enough to whet your appetites, The CW have also released a glimpse behind the scenes, including interviews with the key Arrowverse stars involved. Check out the clip below to discover some surprising links between the principal actors and some further insight into how each of the characters will be portrayed in this musical dream world:

Musical episodes work best when the songs are integral to the story, revealing each character's innermost thoughts in a way that just wouldn't make sense in more conventional narratives. Fortunately, everything that we've seen so far indicates that 'Duet' will genuinely move both Supergirl and The Flash forward in brave and bold new directions, hearkening back to examples from other shows such as Scrubs and Buffy the Vampire Slayer.

Get your jazz hands ready for when the Arrowverse musical crossover kicks off in Supergirl on March 20, before continuing in The Flash on the folllowing day.
