Someone please correct me if I'm mis-remembering -- I believe that all of the numbers for this year's Tonys were live and all of last year's except for the "A Chorus Line" opening number outside Radio City, which was taped beforehand.
The opening number for the Tonys featuring the 42nd Street revival on the subway was recorded beforehand as well.
"What was the name of that cheese that I like?"
"you can't run away forever...but there's nothing wrong with getting a good head start"
"well I hope and I pray, that maybe someday, you'll walk in the room with my heart"
