I usually opt more for the movie soundtrack versions of Broadway musicals, but out of that I've always really liked West Side Story and Little Shop of Horrors. I also like Wicked, because it's fun.
Huh? Signature? What's going on with that signature?
My favorite Broadway show is The Phantom of the Opera. I was lucky to see ot with the original cast in NYC at the beginning of 1989. Then, there is The Sound of Music, Fidler on the Roof, Cabaret, Chicago, A Chorus Line.... and many more.
