most of Gypsy... I haven't seen many regional productions that haven't copied the original coreography...
Beauty and the Beast... most of the numbers... and the costumes... even though it's illegal to copy anything from the Broadway production, contractually... people do it...
I'm sure Spring Awakening will be copied when it gets released for other theatres...
the finale of Ragtime... with the silhouettes of the company dancing across the stage in the background with the speaking characters in light in the center of the stage...
Dolly's Entrance into Harmonia Gardens...
a LOT of West Side Story... when the original choreography is copied... espec. the finale of that show.
CATS... ...enough said.
Phantom...
Saigon...
any giant imported British show from the 80's...
that's a really big mic...
