'The Flash' & 'Supergirl' Musical Crossover Premieres in March; Here's Everything We Know!

When the musical crossover episode of The Flash and Supergirl was announced last year, JJJ rejoiced.

And we’re STILL rejoicing because the list of characters who’ll be performing was just released and it’s a dream come true! Seriously, this a Broadway musical we always knew we wanted and need in our lives ASAP.

The crossover event, which will premiere on March 20th and March 21st, will start at the end of Supergirl, saving most of the musical action for The Flash.

Those singing are: Grant Gustin (Barry Allen/The Flash), Melissa Benoist (Kara Zor-El/Supergirl), Jesse L. Martin (Joe West), Victor Garber (Dr. Stein), Carlos Valdes (Cisco Ramon), Jeremy Jordan (Winn Schott) and John Barrowman (Malcolm Merlyn) will all sing.

We are ready to watch this crossover now!
