One that failed to take off, was the 1976 B'way musical, 1600 Pennsylvania Avenue. Opened and closed in under a week!

I've never seen Les Miserables as a musical, but it just doesn't sound right. A tragic Opera, yes, but a musical?
Guys and Dolls, the movie. Marlon Brando wasn't much of a singer.
I generally don't like musicals; one minute people are talking, the next minute, they're singing. However, of all the musicals I've seen, nothing was as good as Les Miserables (on Broadway).
