Early in her career in 1962, she performed before an audience of over 13,000 at the popular outdoor "Italian Night" concert series at Lewisohn Stadium in New York under the direction of conductor Alfredo Antonini. Later in her career she added operetta and musical theater to her repertoire, appearing in The Merry Widow, and The King and I. She also recorded Rodgers and Hammerstein's Carousel with Alfred Drake. Peters never officially retired and gave occasional recitals later in life. Personal life Peters was briefly married to baritone Robert Merrill in 1952, later admitting she had fallen in love with the voice and not the man. The two divorced amicably, remained friends and continued to perform together in opera and recitals. She
