He was visibly taken by the university choir, who sang two songs during the evening, "Children Will Listen" and "Sunday", and then returned to reprise "Sunday". During that final moment, Sondheim and I were standing, facing the choir of students from the University of Utah's opera program, our backs to the audience, and I could see tears welling in his eyes as the voices rang out. Then, all of a sudden, he raised his arms and began conducting, urging the student singers to go full out, which they did, the crescendo building, their eyes locked with his, until the final "on an ordinary Sunday" was sung. It was thrilling, and a perfect conclusion to a remarkable evening – nothing ordinary about it.
