Last cover band I was in had about 120-150 that could be hauled out for a gig.
Some gigs were two 25-30 song sets and that would require a fairly deep play list.
Playing weddings also added a bunch as there were always requested tunes that weren't really in our playlist.......some of them were downright freaky and scary......I still have nightmares about the song "Daddy's Hands" being used for a father daughter dance.....friggin creepy.....actually having typed that, I feel I need to wash myself.
