Passion - tears me to bits.
Sunday in the Park - loved it since I saw the original, but I actually almost lost a bit of control

during "Lesson #8" in this revival.
Light in the Piazza - ...oh boy... "Love if you can, oh my Clara! Love if you can, and be loved." Holy moly...
Grey Gardens - "it's my mother's house..." again, holy moly...
Once On This Island - can't even SAY: "There is an island, where rivers run deep" without a bit of a choke. I saw this a few times in previews and a couple of times during the run and think it's just a beautiful and deeply spiritual show.
's all I can think of for right now.
