Here's a Sneak Peek at 'Supergirl' & 'The Flash's' Musical Crossover

In what is sure to be one of the more memorable musical events of the year, we will finally get to see our favorite television superheroes flaunt not just their super speed or telekinesis, but their other power: singing.

The casts of both hit series The Flash and Supergirl, have long employed more than a few seasoned Broadway stars. Now, they come together in song and dance to defeat Glee's Darren Criss, the evil Music Meister, who sends our protagonists away to an alternate reality where life itself is just another day of sun and one giant musical number.

Watch The Flash ​x Supergirl musical episode teaser below.
