Do you do them? How often? I'm doing one today with a band that I've never met and only got a song list with the keys they do them in a week ago. It's an evening gig at a town common in Stoughton, MA. The songs seems easy enough so I think it will go well, despite not knowing the other guys or rehearsing with them. I like the idea of only having to sing 6 or 7 songs because the others all sing.
