She introduced a new song, "That's Why A Woman Loves A Heel", in October 1945. By 1948 Boyar had appeared on every overseas radio network. Boyar entertained at Ciro's in Mexico City and the Hotel Nacional in Havana. Among her numerous nightclub engagements was a December 1955 performance at the Viennese Lantern, at 242 East 79th Street in Yorkville, Manhattan. A lawsuit was taken out by an angry tenant who resided above the club. He contended that Boyar's bongo drummer kept him awake.
