Like so many others here, I do it because I enjoy the positive response I get from the people I play to.
I like variety. I am not a big band guy, but I play some big band. I am not a blues guy, but I play some blues....same with just about every genre of music except rap and hip hop.
There was a time it became less than fun...and that was when I was doing 6 nights a week for a year in a fine dining restaurant. The same ol' same ol' got to me and management kept me reigned in.
Now the fraternals, military groups, homeowner associations, private parties, assisted living and nursing homes provide a variety of places to do a variety of music and test my entertainment skills.
I also enjoy going out seeing other guys doing what they enjoy most...or maybe, 2nd most.
