At 51, I'm stuck right in the middle of wanting to join a band and wanting the time to myself. Have been in several bands in the past, and absolutely miss the buzz of being on stage. What I don't miss is getting home at 3am on a Sunday morning in the winter, and subsequently being tired for the rest of the day.
I'm at the stage in life where one child has left home, and the other will soon enough. He's such a good kid (17) to hang around with, and he wants to spend time with his dad. That to me is more important than finding folk to jam with at the moment. I still play often in my wee music room, and that keeps my playing at a questionably reasonable level of competence.
I dunno. Maybe I'll get back to it in a few years. There aren't much options where I live for new projects anyway 😞
