It's fun to change the songs up from night to night. One of our favorite bands, the Grateful Dead, were masters of this. When it's a festival set and we only have a short amount of time, say 45 minutes, we try to play our barnburners and best overall stuff. And hopefully work in some of our best original material as well. For smaller acoustic gigs and longer nights where the crowd effects the show the most, the set list may be completely different. I can think of many times we've gone off the set list and played certain songs because people we knew in the audience would like them.
This is an example of one of our recent set lists. We scatter the originals throughout the night and go with what the crowd wants. We'll do the occasional request if we know it will work.
