The script for the Broadway edition went through so many re-writes that it really is a cut-and-paste job.
The screenplay for the movie improves on it a lot, but the screenplay is owned by Columbia pictures and you can't just put it on stage.
The movie also cut a few of the better Jule Styne songs like "Cornet Man" and "The Music That Makes Me Dance" but these were not at all in the Fanny Brice style.
Barbra's rendition of "My Man" at the end of the movie is also not the way Fanny sang it but it does have power.
Still I regret the loss of the 7 songs cut from the movie and don't find any of the new songs written for the film to be improvements.
FUNNY GIRL was a smash hit on Broadway for the 18 months Barbra stayed in it and did OK for another year with Mimi Hines, but the stage show is not as strong as its reputation and original cast album would lead you to believe!
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
