MEMORABLE MOVIE MUSICAL PERFORMANCES FOUND AMONG MEMORABLE NON-MUSICAL MOVIES

Working from the top of my head and I set a few limits: 1) Performance must produce/alter the sound of the song - leaving plenty of great dancing (ex. Pulp Fiction twist contest) and montages (ex. Scarface money laundering) for other lists. 2) Only movies, no TV (lest this be a M*A*S*H and Arrested Development love fest). Suggest your favorites!
