I can only speak for myself, but public school did nothing for me musically. I got the impression a musical career was frowned upon. But in the arts, resistance can often be the strongest inspiration.
I think I had kind of an advantage. When I was growing up, my dad had just got out of jail and he had a great record collection. He had - it was all - these were the songs. So I heard a lot of these songs, like, my whole life, so for me it was easy. I already knew what I was going to sing.
