It depends - are they intelligent theatre fans or just people who are going to a show because you're paying?
If they love theatre and appreciate intelligent theatre:
'night, mother
Rent
Fiddler on the Roof
Pacific Overtures
If they're easily amused and don't care:
Bombay Dreams
42nd Street
Wonderful Town
UNDER NO CIRCUMSTANCES should you waste your money on Dracula, Mamma Mia, The Lion King, or The Producers.
You said you like dancing - Wonderful Town and 42nd Street have pretty decent choreography - but for some reason the choreography of Bombay Dreams always makes me want to get up and join them. And it's not as bad as everyone says - it's much better than some things on broadway right nwo.
