Frank Sinatra crooning by Nick Amado. Music, lyrics and video editing by Jon Kaplan and Al Kaplan (Conan the Barbarian: The Musical, Silence! The Musical).
Actual YouTube comment by “Psychicwhoosh”: “I saw Sinatra and Dean Martin perform this at the Desert Inn in 1960. It was magical. Dean was such a ham. He kept chasing Sinatra ’round? the stage with a needle trying to prick his hand for a blood sample.”
