AudreyTwoTwo:
You probably only have the old Geffin CD release of the OBC (mine had a horrible glitch in it, and would skip "Steppin to the Bad Side", and mess up the breaks if I wanted to go forward a track or back).
You really need to find the newer 2-CD version released by Decca Broadway. It adds three songs that were not on the original release (or the LP), including the "It's All Over" sequence that leads up to "And I Am Telling You".
That, and the Tony performance actually is shortened (though it still is an amazing 8 minutes). It cuts out all of Michelle's parts, but they are in the CD version.
Xanadu! Can't cry on cue!
