Thanks for the fast responses.
I play in many different genres...

-A lot of 10's-20's-30's-40's Ragtime, Broadway, jazz, blues.
Stuff like "All Of Me", "Hernando's Hideaway","Some Of These Days", "It Had To Be You", "Dream A Little Dream Of Me", "Makin' Whoopee", "St. Louis Blues", "St. James Infirmary", "Bye Bye Blackbird", etc, etc.

-A LOT of 50's-60's-70's country by J.Cash, M.Haggard, G.Jones, W.Jennings & others.

-A little bit of Bluegrass, a little bit of Gospel

-Older rock like F.Domino, B.Holly, Everly Bros, Beatles, CCR.

-Some seasonal stuff, [like Christmas], and some novelty songs.

-I would do a few Ventures instrumentals if I had bass, drums & rhythm.

Kind of a 'try-to-please-any-crowd' repertoire, as the senior citizens particularly
love tunes that take them way back to past times...it's amazing how many know the lyrics and give a good effort at singing along.
