"409" is a song written by Brian Wilson, Mike Love and Gary Usher for the American rock and roll band, The Beach Boys. The song features Mike Love singing lead vocals. It was originally released as the b-side of the "Surfin' Safari" single. It was later released on their 1962 album, Surfin' Safari, and it was also on their 1963 album, Little Deuce Coupe.
The "409" of the song is the Chevrolet 409.
The song was inspired by Gary Usher's obsession with hot rods. The group's treatment of this, one of their first major releases recorded April 1962 (released June 4th), reflects their influence by black r&b acts popular on Los Angeles radio stations at the time and shows a more raw approach to rock and roll than their much more polished releases continuing in 1963. It stayed one week on the 'Billboard' Hot Hundred at number seventy-six in October 1962.
409 is a Twelve bar blues.
