I can't tell you anything about the beginnings of Bill Chinook's career, but i did work with him in the late 80's, providing the PA and mixing his shows that he did up here in Maine. I don't know that I would say we became friends during that time, but it was more than just a business relationship. Bill lived nearby to me and I would see him at Radio Shack or at the hardware store, and we would always chat for a while.
Bill was a talented and passionate musician for sure, but honestly I don't think he was on the same level as Springsteen. He was however, a consummate professional, very demanding of his crew, his fellow band-mates, his producer, and mostly of himself. He was also gentle and kind to everyone he met, and he really took care of his 'band of brothers' while out on the road. He gathered quite a following up here in Maine for many years.
I was fortunate enough to see him perform at one of his last shows and caught him during a break to talk to him about the old times. He seemed very down and I asked him how things were going. He just said it isn't like the old days is it? I had to agree. I do wish I had followed up with him, in retrospect.
