I was surprised he was 87 as well. I saw Galper a few times over the years but it's been a long time since I last saw him perform. I really enjoyed his playing with Phil Woods.
He had been living in upper state New York around Callicoon, right on the Pennsylvania border. I saw on FB that he then had a afternoon gig at Rafter's Tavern, a local spot. caught him once there with Billy Mintz on drums. Can't remember who was on bass. Fun hour.
