Right now, the stage door is very...not busy...b/c of the construction on the Richard Rodgers, the barricades aren't up, and usually there's just a couple of people waiting. So for that reason, it's not so obvious to the actors as they walk out that people are waiting for them, so it's important to speak up as they exit, and w/ there not being so many people there, don't just assume someone else will ask.
"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
