Was this really cut in the original production? Heh, never knew that.
This section was in the licensed version of the score we got in high school. We of course cut it, but it was there. I always assumed it was part of the nightmare, but never on the recording.
Let's see the part in question, at least the part cut from the OBCR, in measures is...okay, the whole Somewhere sequence has continuous measures (from the "under dialogue" prior to "I Will Take You Away..." through the ballet and song and nightmare and Maria & Tony singing at the end)...so the "Procession and Nightmare" which directly follows "Somewhere" the last note of singing starts at measure 160...the measures in question are measures 195-206. The OBCR plays the full measure 194, then goes directly to a pick-up to 207.
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
