It’s been so long since I had a gig I can’t remember my policy.
😆😆😆 Same here!
Josh and Gabe would usually huddle about it on set break, and compromise on a couple tunes with whoever wanted to sit in or sing a couple with the band. I can't say what happened to Bill TGO ever happened to us, or how measured the response to it would have been.
Probably the most fun sit-in I remember during my time in the band, both of my predecessors on bass joined us onstage during a show last year. The original bassist in the band, his replacement, and me, all at once. It wasn't planned, but it was fun. We posed for a picture together later.
