Sounds like you had a great 'maiden voyage,' Gern. And having people request a song you've just finished playing is also par for the course. (Many seniors have no cognitive impairment except for short-term memory lapses.)You seem to have a good sense of what songs will go over well, and all of the songs you listed (including "Misty"*) are ones for which I often get requests from retirement and nursing home residents.

*Wasn't "Misty" written in the '40s or '50s, BTW?
