Half of our new songs come either from random requests from the crowd, or a song that the guitarist launches into on a whim. Others will be picked out when we hear them on the radio maybe. We don't add stuff that often, but then we pick songs from a repertoire of many years together. We never use a fixed set list - just call them out as we go. We have learnt a few proggy tracks recently - showing off really, but having a tasty guitarist with an ElectroHarmonics organ pedal lets us tackle some material that you won't hear other bands doing
