Agree about Bernadette Peters in HELLO, DOLLY and Kristin Chenoweth in SHE LOVES ME. Chenoweth would be a riot during "Ice Cream" and "Where's My Shoe?"
I'd be glad with all these:
Jennifer Holliday and Nikki M. James in CAROLINE OR CHANGE.
Anne Hathaway in FLORA THE RED MENACE.
Donna Murphy in KISS OF THE SPIDERWOMAN.
Jane Krakowski in MACK & MABEL.
Meryl Streep and Jane Krakowski in ANYONE CAN WHISTLE.
Anne Hathaway in SONG & DANCE.
