 Endo conducted one of the first Live from Lincoln Center programs in 1976 — a live, televised, complete production of Tchaikovsky's "Swan Lake", starring Mme.Makarova and the American Ballet Theatre.It was simulcast in FM stereo on NPR, and because it was televised live, complete with three twenty-minute intermissions, was quite possibly the longest ballet telecast ever shown in the United States up to that time (three-and-a-half hours counting the intermissions).
