Frawley made two final on-screen appearances before his death. An appearance on I've Got a Secret consisted of contestants guessing Frawley's, "secret," which was that he was the first performer ever to sing "My Melancholy Baby" in 1912. He then performed the song one last time. His final on-camera performance was in October 1965, making a brief cameo appearance in Lucille Ball's second television sitcom The Lucy Show with Frawley playing a horse trainer and Lucy commenting, "He reminds me of someone I used to know." (Vivian Vance, who by then had left The Lucy Show except for an occasional guest appearance, does not appear in that episode.)
Hollywood Boulevard and Ivar Avenue
On March 3, 1966, Frawley collapsed of a heart attack while walking down Hollywood Boulevard after seeing a movie, Inside Daisy Clover. He was dragged to the nearby Knickerbocker Hotel, where he had previously lived for many years, by his male nurse — a constant companion since his prostate cancer operation more than a year before. He was then rushed to the nearby Hollywood Receiving Hospital (now the Hollywood LAPD Precinct) on Wilcox Ave, where he was pronounced dead.
