If you're interested in Musicals, there's a bit of a forum at http://www.musicals.net/. Cowpie is a good place for country lyrics, but they don't really have a discussion forum. I'll betcha most of us here would say that the Mudcat is the most appropriate place to discuss songs recorded by the Hoosier Hot Shots. Start a thread with the song title in the thread title, and see what comes up.
