@Eva,
Oh my!!! Rocky Horror.
I still sing from that all the time. It was a cult here for many years....there was a cinema that showed it every Friday night, and people would dress up and attend regularly and sing it all and such.
The stage production lasted forever, too.
I love My Fair Lady....the script is rawther fine, you know (I like Shaw, and it wasn't too gussied up for the film).
I sing from that all the time, too.
I dislike Sound of Music intensely (sorry Fox), but I can sing all that, too, since it was my mother's favourite, and we had the cast recording, which she played again and again and again and again.....
It wasn't a musical, but I do love the soundtrack from Diva...especially that lovely aria from La Wally.
PS: The hamsters are doing well tonight....one of the ads below, for me, is for an upcoming Adelaide production of "Orpheus in the Underworld"!
