If the band is flipping through their books, paper or electronic, to choose what tune to play next, that isn't a performance worthy of the term. It's a jam session. Which is fine, but hopefully nobody is paying to listen to it.

I agree, but sometimes you don't know all of the details of a gig before agreeing to play, especially since I'm not the top call bassist in my locale. Then you put on the best show you can under the circumstances.
