"...I remember the annual showings of Peter Pan-Mary Martin ??..."
Ah yes, one of my faves; I was fortunate enough (or perhaps you could say, old enough) to have seen Mary Martin perform Peter Pan live on stage, at the Marine's Memorial Theatre in SF.....also lucky/fortunate/ole enough to see her perform in South Pacific and Annie Get Your Gun [with John Raitt (and since I've always been such a Mary Martin fan, I feel she was waaaay better than the original, Ethel Merman)].....also that same season I got to see Julie Andrews and Richard Harrison in My Fair Lady.....my mom wanted to get me outta the movie theater and into the real theatre (lol); of course, back then, these plays were not called musicals, but light opera (predominantly singing, but with a tad of spoken dialogue).
ahhhhh, to go back in time.....youth really is wasted on the young ... lol
