He started his career in the 1950s as a composer and record producer. His first notable hit was a 1959 Christmas novelty song, inspired by "The Chipmunk Song", titled "The Happy Reindeer" credited to Dancer, Prancer and Nervous (No. 34, Pop) issued by Capitol Records.[5] In the early 1960s, Regan recorded "Joan of Love", backed with "Adults Only", which was released under the name Russ Regan.[citation needed] He also recorded "Calling All Cars" under the name Davy Summers for Warner Brothers with producer Sonny Bono.[citation needed] In the mid-1960s, he was drafted in to help form a musical direction for Warner Brothers' fledgling pop/soul music subsidiary, Loma Records.[citation needed]
Russ Regan played a major role in the careers of a number of recording artists, as he headed up labels such as Uni, 20th Century and Phonogram Records.[3] Dozens of recording artists, including Elton John, Neil Diamond, Barry White, Olivia Newton-John and The Beach Boys had Regan to thank for opening the doors for their success.[6] One of his most surprising successes while at UNI was South African trumpeter Hugh Masakela's "Grazing In The Grass" in 1968, which sold over a million and reached the top spot in the Billboard pop chart.[citation needed]
