Query: The Joys of an Excellent Musical!

With Broadway turning to revivals in place of the current poor excuses for new musicals, it is a pleasure to listen to one of the classic African-American musicals of the 1970's. Cleavon Little and Melba Moore were spectacular in this musical production. It is great to go back to musicals whose lyrics you could understand and which did not have four letter words throughout!
