Amazing, sad, Campbell was a bar buddy of a few of my friends in late sixties and early seventies. He sat at our table many times I recall. Paul Siebel (folk artist of that period)got to know him pretty well I believe. The notorious bar was Kettle of Fish on Macdougal St. — sometimes the Blue Angel on Bleecker St. Sorry that I don’t remember anything about him (I thought he had a past in the Merchant Marines, but could be mistaken).
