How can you not want a musical episode from Arrow, The Flash, Supergirl, and Legends of Tomorrow. Like, you have Grant Gustin and Melissa Benoist from Glee (and Blake Jenner now, too), and then you have Jeremy Jordan, Jesse L. Martin, Laura Benanti, Ciara Renee, Arthur Darvill, Victor Garber, Colin Donnell, and John Barrowman who are theatre/Broadway people (Colin and John played the same fucking role in Anything Goes, btw, like father like son), Colton Haynes who can sing, Caity Lotz and Keiynan Lonsdale who are dancers and singers, Carlos Valdes whose a singer and musican, AND Andy Mientus is a theatre/Broadway person who was ALSO on Smash with Jeremy.
Just imagine a musical episode from each show and then think about a giant crossover.
I mostly picture Barry doing a huge tap number, there being a flashback/hallucination/dream where Tommy sings about being Oliver’s best friend, and Hartley having a dramatic ass soliloquy about anything (probably some angsty stuff with Wells).
Guys, the possibilities.
