Diamond, together with his band the 24 Karat Diamond Band, played many classic rock and disco-era songs. He often called himself the "Love Doctor," getting the name from his radio show, Saturday Night Fever which he hosted Saturday evenings on 96.1 WJYE (now WMSX) featuring love music. His success in Buffalo led him to receive offers to lead shows in Las Vegas, which he declined due to his preference to stay in Buffalo.
Diamond played with the Goo Goo Dolls live, as well as recording with them on the tracks "Down On The Corner", "Never Take The Place of Your Man", "My Girl", "Do You Believe", and "Bitch" (Rolling Stones cover). Diamond and the Goo Goo Dolls performed "Bitch" on the 1993 AIDS-Benefit Album No Alternative produced by the Red Hot Organization. Diamond met Goo Goo Dolls' bassist Robby Takac after Takac moved into the apartment directly below him in a Buffalo apartment building.
Diamond died on January 4, 2015, a few days after being hospitalized due to heart complications that prevented him from performing his annual New Year's Eve show. As Diamond kept details of his personal life private (to the point where no official obituary was published), his exact age is unknown.
