(1960-1965)
You're right. He moved on after the 64/65 season. He began with the very first regular show I believe, in 1960. Won 5 Emmies in a row, too. Always gave credit to "the big guy" (Andy) for his success. As I recall, at one Emmey award he said, "Well, if it wasn't for the Big Guy, I would be parking cars out here tonight".
