Leonard Bernstein conducts the Boston Symphony Orchestra for the last time at Tanglewood.

He conducts Benjamin Britten’s Four Sea Interludes and Beethoven’s Seventh Symphony at the Tanglewood Music Festival, where he first studied under BSO music director Serge Koussevitsky 50 years earlier. Longtime usher Lynne Harding subsequently recalls, “We knew he wasn’t well. Towards the end of the concert, he wasn’t conducting at all: he was leaning on the back [of the podium], his head was moving, and the orchestra was playing and we were all crying.” Bernstein dies in New York City two months later.
