Gallagher went to court and put a stop to that.
He had a really odd family situation. I remember reading about it during the lawsuit. He was always the good son, excelled at school, had a great career, etc. His brother was, well, not like that. But the parents always made it very clear the brother was their favorite.
They pushed him into letting Ron tour using his old material. Gallgher agreed under certain conditions and Ron violated all of them.
I’ve seen them both perform live. He brother was terrible at the act.
