I haven't seen very many broadway musicals at all… The ones I know are Hamilton, Newsies, Les Mis, Ride the Cyclone, Dear Evan Hansen, The Pirates of Penzance, The Phantom of the Opera, My Fair Lady, The Scarlet Pimpernel and Guys and Dolls. (And feel free to recommend musicals for me to watch! I'm going to start a list! Some of the musicals on my list are Six, Heathers, Be More Chill, and Wicked.)
So, yeah, If you would like to rp maybe pick one of those, cause they're the only ones I've seen so far.
