Mark and Scott's kiss on the Tony's still takes the cake for my favorite moment, I was alone in my apartment screaming and clapping!
But in regards to actual production numbers...
-Grand Hotel, "We'll Take A Glass Together"
-The Lion King, "The Circle Of Life"
-Kiss Of The Spider Woman, "Where You Are"
-Chicago (1997), "All That Jazz/Honeyrag/Finale"
-Gypsy (2003), "Rose's Turn"
I'm sure JHo's "And I'm Telling You..." was fab!
If Lincoln were alive today, do you think he'd be pleased with his tunnel?
