Perhaps Feldman didn't truly appreciate the imagery of Tonya Pinkins slamming the iron down on her sex.
I would agree that The Act probably deserves a place on that list most likely instead of The Life. And A Chorus Line deserves spot #1 not only for the performance, but the honor it was awarded by its length and placement in the telecast.
And though I'll probably get flack for this, I'd replace Bernadette's Rose's Turn and Spring Awakening with On the Twentieth Century and Rent.
Honrable mentions:

Best Little Whorehouse in Texas
On the Twentieth Century
