I went to see the touring show of "Stereophonic" last weekend, and they were selling copies of the script in the lobby so I grabbed one.
The touring production is just under 3 hours while the broadway original is 3 hours, 10 minutes, I'm interested in seeing what was cut.

The script is interesting in how they convey the stage direction.
The stage is set up with a raised recording booth behind glass, with a control room in front. You often have overlapping dialog between the booth and the control room.
So in the script, all the booth dialog is on one side of the page and the control room is on the other, with overlapping lines marked with "//".
