Thanks for the lead, Quincy. Don't know why I didn't think to do a search on the movie title. I can't say for sure whether the actors were actually the singers. For the purposes of the story, they didn't need to be very good.

John, that seems as if it could be the one. I think it may have had some risque verses to it. I have sat through the show twice and am still trying to figure out the lyrics. (I think it may be time for some new batteries;-)
