"Fun, Fun, Fun", written by Brian Wilson and Mike Love, was a hit single by The Beach Boys that was released in 1964 on the band's album Shut Down Volume 2.
The song was written by Brian Wilson and Mike Love about Shirley England, the daughter of the owner of radio station KNAK in Salt Lake City, Utah (not to be confused with the call letters now assigned to a station in Delta, Utah) where she worked as a teenager. She borrowed her father's Ford Thunderbird to go study at the library. Instead of driving to the library, she ended up at a hamburger stand. When her father found out he took the car away. The next day she was at the radio station complaining about it to the staff while The Beach Boys were visiting and they were inspired to write this song.
The Wilsons' father, Murry, always the critical conservative, denounced the whole idea for the song as immoral, and tried to prevent the group from recording it. The song, backed by a single-only mix of a cover version of Frankie Lymon and The Teenagers' "Why Do Fools Fall In Love", became a top-five hit. This argument set the seed for further deterioration in the family. It finally led to Murry being sacked as The Beach Boys manager a few months later when "I Get Around" was about to become the first number-one single for The Beach Boys.
