The CW is REALLY banking on this musical crossover event between ‘The Flash’ and ‘Supergirl’!  Well, we’re just a week away from these former ‘Glee’ stars belting it out on their new superhero home shows.  Though ‘Supergirl’ will just barely touch on the crossover, ‘The Flash’ promises to be a full-on musical presentation, drawing in various DC show cast members as John Barrowman, Victor Garber, Jeremy Jordan, Jesse L. Martin and Carlos Valdes, all of whom have musical theater experience.  Joining the fun will be Darren Criss, a fellow ‘Glee’ alumnus as The Music Meister, a character that originated on the animated series ‘Batman: The Brave and the Bold’.

Criss described thge episode as:

So the Music Meister has plans for them, he’s kind of stringing all of the main character along. Particularly the couples, to maybe teach them a lesson? That’s what he says.”

Check out the two trailers below:

As a bonus, here are some still images from the episode:
