Most times for any 1 or 2 hr gig I use registrations set up in folders for each genre of music, eg: Latin, Big Band, R&R, Ballads, Traditional, Irish, Jewish, Christmas, Italian, etc,.... I never make a set list instead let the gig drive your performance and by drawing from all your folders you can pick & choose what songs you want to play as you go along in rapid fire with just a few seconds in between for banter to keep the pace flowing,.........the only thing I have in the MFD is a list of Mp3 backing tracks that I also use at times depending on the venue that I sing and play on top too... larger jobs is a whole different story which involves my laptop too into the mix.
have fun do it the way its comfortable for your needs..
