Supergirl and her superhero cohort the Flash will have to be brave and bold against the evil Music Meister, the classic DC villain who can control others through song, in the upcoming musical crossover between Supergirl and The Flash.

At the 2017 winter Television Critics Association press tour, executive producer Greg Berlanti announced Music Meister as the villain of the anticipated crossover. The role has not yet been cast, but showrunner Andrew Kreisberg mentioned triple-threat Neil Patrick Harris as a possible choice. Harris was the last to portray Music Meister in an Emmy-nominated episode of the animated series Batman: The Brave and the Bold.

“We’re certainly huge fans of [Neil Patrick Harris],” Kreisberg said, “and as the casting process proceeds, we’ll see what happens.”

It’s a happy accident that the CW’s arsenal of DC shows are loaded with legitimate musical talent. Glee alums Melissa Benoist and Grant Gustin lead Supergirl and The Flash, respectively, while Broadway veterans Laure Bernanti, Jesse L. Martin, Victor Garber, Carlos Valdes, Jeremy Jordan, Arthur Darvill, and John Barrowman round out the ensemble cast in all the DC shows. Chyler Leigh, who plays Supergirl’s sister Alex, also sang in a musical episode of Grey’s Anatomy. In addition to acting, Kid Flash actor Keiyan Lonsdale has a bunch of YouTube videos where he sings covers of Ed Sheeran, Ne-Yo, and Drake.

So, yeah, there’s a lot to be excited for the crossover. Fingers crossed Harris can reprise his role.

Supergirl returns January 23 and The Flash January 24 on the CW.
