Let's look at the numbers, shall we?

Seniors under 80, encompasses a range from 65 -79, the mean age is 72. People 72 years old were born in 1939. They were 11 years old in 1950, when the big band ensembles were still going pretty well. They faded through the decade of course, but the "crooners" like Sinatra, Martin, Fisher and Cole performed a similar style of music.

Tastes vary from region to age groups, etc. I think to categorically say don't play that kind of music is wrong. Dancers enjoy a variety of musical styles including big band swing stuff.

Here in Dayton, there are clients I play mostly Big Band material for but then other ones who really prefer Country music. Its important to know what your client wants-and give it to them.

Typically people who enjoy dancing have been dancing for several decades and usually find some of the Big band era material familiar.

Play a lot/play a little...whatever works best for the client....
