If I recall correctly, Cohen was the name Bruce Phillips' step-father. I don't know whether or not he was ever "Bruce Cohen."
Back in May 1973, Debbie Cohen, Bruce's half-sister showed up at a Utah Phillips/Malvina Reynolds concert I produced at Dawson College in Montreal. If I recall correctly, she was changing planes in Montreal, saw something about the concert in the paper, switched her flight and jumped in a cab to the concert. I think it was the first time that Bruce and Debbie had seen each other in several years.
