I am Bob's brother Dan and after listening to the recording I can say without any doubt that it is he. Although I am not familiar with this event, I know Bob was by 1957 very active in promoting his singing career. Although he did have some success as a performer he changed direction and focused on song writing and record production. I joined him in 1962 and together we had a great run with artists such as the Four Seasons, Mitch Ryder etc. Bob passed away September 11,2014 here in Maine where he was in a medical nursing home. Thank you for this forgotten event. By the way, I know Bob and Robert Q. enjoyed a long friendship.
