A lot of story aspects from the show haven't aged that well to be honest, and it's only very loosely based on Fanny Brice's life. I think there's been revival attempts before, but either funding wasn't there or they've had issues finding someone to succeed Barbra.
Funny twist of irony - Beanie was also in the Hello, Dolly! revival starring Bette Midler a few years back. Hello, Dolly!, of course, was the musical that completely shut Funny Girl out of the Tony awards in 1964 with Carol Channing besting Barbra for the Best Actress award. Barbra got her revenge when she was (mis) cast in the film version, however.
