Supergirl & The Flash Musical Crossover With 'The Music Meister' Confirmed

Executive producer Greg Berlanti has confirmed that there will be a two-part Supergirl/The Flash musical crossover and they will be doing battle with The Music Meister.

The Music Meister was voiced by Neil Patrick Harris in the Batman: The Brave and the Bold animated series, but the character has not been cast for the live-action role.

CW president Mark Pedowitz told sources that he was just about to see the script for the musical two-parter, adding: “We’re very excited about it. There’s great musical talent on both shows,” including but not at all limited to series leads/Glee alumni Melissa Benoist and Grant Gustin.
