Although Pons continued to sing concerts after she retired, her greatest acclaim occurred in May 1972, when the news media announced that she would emerge from retirement to sing a concert at Lincoln Center under the baton of Andre Kostelanetz, her former husband. All tickets to the concert were sold within an hour of their availability. The program of the historic concert, which took place on Wednesday evening, May 31, 1972, did not include any of the coloratura arias which Pons sang in her prime, but did include ones more suited to her range at age 74. As she often did in earlier concerts, she included “Estrellita” among the songs in her program, and received a prolonged ovation after the concluding note.
