I depped on a covers gig a couple of weeks ago. A lot of the same tracks that have been listed on this thread. I was given a prospective setlist a couple of days prior to playing. On the night, however, there were a few tracks thrown in without any prior knowledge! (Barry White's "the first, the last, my everything", Queen's "Crazy Little Thing", etc.) I had to try and remember how they went. Thankfully, I got through it, but it was pretty unnerving. I was offered a place as the regular bassist if I wanted it, so all was well.
