I had my 75th birthday last June and I am still doing what I love. I have played all types of music during my life: pop, blues, country, folk, etc. About three years ago, I decided that I would like to try playing jazz. I wasn't sure if I would be up to the task but I answered an ad on the JoinMyBand website and three years later, I am still with them. We don't work very often but when we do, they are usually enjoyable gigs.
It would be great to work more often but at least we are working. Don't give up and remember Churchill's immortal words: "keep buggering on".
