The Distinctive Baritone said: "What’s cut again? Geraniums and Stonecutters?"
Musically: most of "Give it to 'Em Good Carrie," "Geraniums in the Winder" and "Stonecutters Cut it on Stone."
Text-wise (*SPOILERS* for a nearly 80 year old musical) and this is from what I can remember from a week ago: The entire Act 1 closing scene post "Soliloquy," Mrs. Mullin coming back and seeing Billy's dead body and Julie allowing her to have her goodbye, Jigger's "seduction" of Carrie has been cut in half, the moment in "What's the Use of Wondering" when Julie discovers Billy's knife, the entire card game before the robbery when Billy gambles away his share of the money, and, infamously, the entire "It is possible, dear, for someone to hit you..."
There are also many, many more lines throughout the script that have been cut as well, but those are more annoyingly unnecessary, rather than wrong headed like some of the ones above.
"Sing the words, Patti!!!!" Stephen Sondheim to Patti LuPone.
