I actually had a "Proctor and Bergman" LP (anyone remember those?) that someone purchased for me as a child. Some of it was funny, but because it was recorded before live audiences, the audio was poor. It was like sitting in the back row and hearing more of the laughter than the comic lines that were being laughed at. Had no idea either of them were still alive ! RIP, funny man.
Philip Proctor, 71, has been a prolific voice actor in cartoons for years.
David Ossman, 75, still writes and produce radio plays for NPR and theater.
Philip Austin, turning 71 next month, still writes, and has done voice work also. (I guess this makes him the "baby" of the group.)
