I saw it at the very end of its run. Robert Sean Leonard was Harold Hill, and even though I respect his work as an actor very much, he was very subdued at the performance I saw. The production seemed to be moving by rote--kind of competent but not much else. I am old enough to have seen the origina production---which was amazing! Full of vivid, live performances, exciting staging by Morton Da Costa, and of course, Robert Preston's remarkable performance-so full of energy---sometimes it seemed like the musical itself was trying to catch up to him. I felt that in 2000, they were "doing" The Music Man, rather then letting every moment count.
