My pal Bob Claster thinks that Ross Bagdasarian was singing live to a pre-recorded track on the Sullivan show, not lip-syncing. He may be right but that would still give Mr. B. the problem I described of figuring out when to stop moving his lips as the track faded. Anyway, you can decide for yourself if he's singing live…if you care.
A number of folks wrote to ask me if the lady in the clip was either Noel Neill or Phyllis Coates, both of whom played Lois Lane on the Superman TV show of that era. I don't think so, and not just because they were both based in L.A. and Ed's show was done in New York. I don't think it looks that much like either one, though I see the resemblance to Ms. Neill that causes some to wonder. I think it's Jack Benny dressed as a waiter.
