I fully agree with Bill's point about not playing pre 1939 music. When I started in this business the done thing was that when playing for elderly audiences give-em plenty of the old Victorian drawing room ballads like "Come into the garden Maud" amd "Drink to me only with thine eyes".You know the sort of stuff I mean.

One day I began to realise that I was also getting older and that the people I was now playing for were no longer from pre -1914 but came, by and large, like me, from the Big Band era. Now I find that
(horror of horrors) there are some who don't like Glenn Miller. So it's a case of moving with the times , which also being an early rock'n'roller, came fairly easily.
Whilst the current crop of wrinklies don't care too much for Rap , Garage, Hip-Hop and the like they do like plenty of 70's and 80's Disco stuff. You know, when music was still largely about the tune.

Being 81 myself I may still have to do some of the'orrid stuff if I keep going much longer. to keep up with the times!!!
