If I had to live again I would do exactly the same thing. Of course I have regrets, but if you are 60 years old and you have no regrets then you haven't lived.
Forty years ago, my life in music was substantially different to today. I went out every night with my guitar seeking a place to sing, a floor on which to lie, some love, some food, a lot of wine. There was no business, no gigs, no questions, no P.R., recording, life was simpler, I was poor and young and hungry. Today I am a lot more focused on The Song.
