I play sometimes on the grand piano at the nursing home where my mother is a resident. The ladies there aren't too picky, but they generally like "pretty" songs. Come Sail Away, Love of My Life by Queen, Summer Breeze by Seals and Croft, Let it Grow by Eric Clapton, etc, etc... One day I opened with a Green Day tune I had learned, and one of the old ladies got up, hobbled over and asked me not to play because she was trying to sleep! Made me laugh; maybe she just doesn't like Green Day!
