Um, I think they re-broadcast it in the 80s because we taped it too. But the Mary Martin version was from the 60s. I saw the live broadcast as a kid. She died in 1990 and was in her 70s.
True story. My aunt was in England in the Air Force. She met Larry Hagman who said "let me take you to meet my mother, Mary Martin." Martin was doing a show in England at the time. Aunt didn't believe him until she actually met her.
We saw the stage version of Peter Pan with Cathy Rigby.
