Guided by Atlantic's star-maker Ahmet Ertegun, Darin's career finally took off in 1958 when he recorded "Splish Splash". He co-wrote the song with radio D.J. Murray Kaufman after a phone call from Kaufman's mother, Jean, a frustrated songwriter. Her latest song idea was: "Splish, Splash, Take a Bath". Both Kaufman and Darin felt the title was lackluster, but Darin, with few options, said "I could write a song with that title." Within one hour, Darin had written "Splish Splash". The single, Darin's first successful foray into the rock and roll genre, sold more than a million copies. His partnership with Kirshner, who was not involved in the writing of that song, ended at that time. He made another recording in 1958 for Brunswick Records with a band called "The Ding Dongs". With the success of "Splish Splash" the single was re-released by Atco Records as "Early in the Morning" with the band renamed as "The Rinky Dinks". It charted, and made it to number 24 in the United States.
