Johnny Carson had a golf pro on his show one night (forget the name), and he said "now thgat you're getting older, isn't it time to think about retirement?"
The pro replied: "I play golf every day. What would I retire TO?"
I tell people that I'm a retired high school music teacher, but that's just a fancy way of saying that I don't teach school anymore. I have made music my business for my entire working life, and there have been "chapters" that have had variations. Teaching was a 10 year variation on that theme, and I have no regrets.
That's the way I see my music career. I will sing until I can no longer do so.
