For many years I was usually the youngest in bands I was in. Very fortunate in getting to play with some people who were better players with more gigging experience than myself which helped me enormously, both musically and socially.
Now it’s a different situation - my main band are all in their mid 50’s to mid 60’s, and although there are maybe 10 years between some of us, the gap seems less as you all get older. The really odd part is that we also have two cellists who are in their early twenties, and even the massive age gap there doesn’t cause any problems. After over 45 years of gigging, I’m very lucky to be working with such great people.
