I guess I'm mentioning all of this to attempt to explain this song. Ed Byrnes was an actor who played in the ABC series, "77 Sunset Strip". On the pilot episode he played a continual hair combing serial killer. The end of the show has him being arrested and sent off to prison to be executed. However, there was huge feedback about the character and, sensing how popular he was, ABC brought him back the next episode. "Kookie" was a character that many could identify with: windbreaker jacket, hair greased up and piled high on his head, and a language that was a cross between Jack Kerouac and James Dean (...think Fonzie from "Happy Days"). He became one of the first TV teen idols.
The show ran from 1958-1964, and this duet with Connie Stevens was recorded early-on in the "Kookie" phenomenon. It reached #4 on the Billboard singles chart in late spring of 1959...
