Hi Joe, I like Mary Garvey's take on this. To me, a good song fest is one where spontaneity abounds. For example, someone might get into "East Texas Red"', which logically leads to "Danville Girl," which can lead into "Hoboes Lullaby," etc. If our noses are buried in a book, that kills the moments when other companian songs emerge. Perhaps the answer is simply planning a good mix: well known group songs for the sing-a-long crowd, but try to add a measure of a free for all, where the more extensive repertoires can add to everyone enjoyment and education. CHEERS, Bob
