Thanks Jerry, good ideas!45 pieces is a nice challenge and you should take breaks too. I always enjoy a 45min play - 15 min break... that way you need a few less songs, people know you are there and with that 45 songs, you can actually go for a longer period of time. Also don't forget to switch registrations more and instead of just playing a song 2 times make it 3 repetitions, that too gets them from 2.7in to over 3 min.
Keep us up to date how it goes!
