In DC lore, the Music Meister can hypnotize people by singing in a high register. He uses his power to settle scores with those who bullied him as a child.


Other warblers: Supergirl’s Jeremy Jordan, The Flash’s Jesse L. Martin and Carlos Valdes and Legends’ John Barrowman and Victor Garber.

“The Flash is already a musical. We just don’t film it,” Tom Cavanagh told a Fan Expo Vancouver audience,  Cavanagh, Carlos Valdes and Tom Felton play guitar on set during breaks. “Carlos is the Lin-Manuel Miranda [Hamilton]” of his generation, Cavanagh said. And Jesse L. Martin is a Broadway star of his generation, headlining in Rent.
Dermott Downs will direct Duet which like the Fall crossover will start at the end of a Supergirl episode and lead into Flash’s Duet. David Harewood’s Hank and Chris Wood’s Mon-el will guest-star in non-singing roles.
Supergirl’s mustical crossover episode airs Monday, March 20th followed by The Flash’s Duet on Tuesday, March 21st on The CW.
