Alley Oop was a popular newspaper comic strip ("the funny papers") about a caveman. This is a novelty song based on the character.
This was written by the country songwriter Dallas Frazier, who recorded the song in 1966 and released it on his album Elvira (Columbia 2552). In 1967 Englebert Humperdinck recorded Frazier's "There Goes My Everything," which hit #2 in the UK and #20 in the US.
Lead singer Gary Paxton recorded this as a solo artist, since he was still under contract to Brent Records, where he recorded as Flip of "Skip And Flip." He made up the name Hollywood Argyles - the recording studio was on Hollywood Boulevard and Argyle Street. When this became a hit, Paxton put together a Hollywood Argyles group, made up of Bobby Rey, Ted Marsh, Gary Webb, Deary Weaver and Ted Winters. This ended up being their only hit.
Producer Kim Fowley and drummer Sandy Nelson bashed empty bottles and wastepaper baskets during the session. Alcohol was a factor.
