 In 1975, the company incorporated as a not-for-profit organization under the current name.At the beginning of 1976, the company began to offer runs in repertory on Sundays, the only day the theater was available, since the New York School of Opera used the space on other days.After several Sunday performances of "H.M.S Pinafore" and "Trial by Jury", NYGASP expanded its repertoire by premiering a new production of "The Pirates of Penzance" on Sunday afternoon, February 29, 1976 – the 30th birthday of the character Frederic from that opera.
