I know that I'm showing my age a bit, but "Shall We Dance" from "The King and I" has always been one of my favorite 11 o'clock numbers, especially the point at which Anna and the King take each other in their arms and begin to dance around the stage. And I happened to see Yul Brynner do this for the very last time, at the closing performance of the revival he was in not long before he died, when everyone knew how sick he was. After the curtain calls, the cast sang "Auld Lang Syne" on stage, and there was not a dry eye in the house.
