It's been a while since I've been to New York, so, I can't comment about a good deal of the actors you're mentioning.
But I can mention:
Judy Kaye
Judy (Judith) Blazer,
Debbie Shapiro Gravitte
Alex Korey
Christine Andreas
Brent Barrett
Karen Morrow
(These people should have shows written for them and they should be working constantly.)
And the mother(s) of them all:
Kaye Ballard
(Except for having appeared in such legendary flops as "The Golden Apple" "Reuben, Reuben" "Royal Flush" and "Molly", the reason why this woman is not a huge star is beyond me. She is flawless with a ballad and peerless with a comedy number. There should be a statue of her somewhere in this great land of ours!)
