Marilyn Miller in SUNNY or AS THOUSANDS CHEER
Al Jolson, Eddie Cantor, Fannie Brice, Sophie Tucker, Ethel Waters and Bert Lahr in anything.
Martha Raye in HOLD ON TO YOUR HATS.
Ditto especially Bea Lillie. Supposedly she was so uniquely demented on stage that no recording or film captures it. And her brand of humour is completely lost.
Merman in GYPSY, naturally. But Susan Johnson's tour of GYPSY even more so.
Carole Landis in A LADY SAYS YES.
FOLLIES of course. Both the original Broadway cast and the tour with Vivian Blaine & Lynn Bari.
Martin & Pinza in SOUTH PACIFIC.
"Christ, Bette Davis?!?!"
