I try to pick songs that would I once listened to regularly but have forgotten about the work on those. Having a few gigs also helps it keeps me motivated to learn some new tunes. I can sight read pretty well so when playing a senior facility it isn't a problem playing the instrumental part, for me it's trying to work on vocals, something I've been doing for a little over 5 years. In the last 3 months i've probably learned 8 new tunes, concentrating on the vocal side of it.
