Here and there I’ve read that Van Dyke Parks played the role of Tommy Manicotti in the television series The Honeymooners. He doesn’t appear in the “classic thirty-nine,” the episodes shown through years of reruns on New York’s WPIX-TV. And there’s no Honeymooners credit for him at the IMDb. But VDP does appear, as I just discovered, in at least one of the “lost episodes,” “The Hero” (February 19, 1955). He was all of twelve. The episode is at YouTube in five parts: 1, 2, 3, 4, 5. So yes, Van Dyke Parks is Tommy Manicotti.
