Aww that's great, fabulous! I've briefly talked to Anthony twice and he's such a sweetie, definitely one of my favorite people in the theatre world, you were very lucky to catch him of all people.
And theatrebaby, too bad, Greg is also one of the nicest, most personable actors, I'm sure you would have had if nothing else an amusing convo with him...but I see why you wouldn't want to bother. I have that issue too a lot, but it helps to try to hear stories about actors to have an idea of who's really nice so I'll feel better about talking to them than others.
"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
