Jim - here's three - "Side By Side" "Paper Moon" "I'm Gonna Sit Right Down And Write Myself A Letter"

Those given, do not go in and assume that your audience wants a bunch
of "old folks" sing-a-long songs. I do twenty to thirty such gigs
per month and every residence is different; and, I know folks who are
in their seventies and eightys who act like they're forty and will not tolerate being treated like an "old fogey." I also, as you may
too, know folks in their twenties and thirtys who act like they
"should" be retired. Keep an open mind and a smile on your face.
Cheers.
