Don't Back Down

1964 song by the Beach Boys

"Don't Back Down" is a song by the American rock band the Beach Boys and the final track on their 1964 album All Summer Long. Written by Brian Wilson and Mike Love, the lyrics describe a group of surfers who "don't back down from that wave", explaining that they "gotta be a little nuts" to show the girls "who's got guts". It was the group's last surfing themed song until 1968's "Do It Again". In 1990, an earlier version of "Don't Back Down" was included on a reissue CD that compiled Little Deuce Coupe and All Summer Long, and in 2014, a new stereo mix was featured on the archival release Keep an Eye on Summer. In 1996, punk rock band the Queers recorded a cover version of the song that served as the lead single for their album Don't Back Down.

The song, in the key of A flat, modulates to the key of A during each chorus, and returns to A flat during the verse. A modulation during the chorus had previously been used by Wilson in songs such as "Don't Worry Baby".

AllMusic critic Richie Unterberger called the track a "relatively little known treasure" and praised it for its "uncommonly anxious lyrics." Music historian Andrew Hickey called the song "one of [All Summer Long's] best tracks."

An alternate version, sharing some of the elements of the final produced version, has a more serious tone. Lines such as "I know what it's like when you feel like backing down" and "Just grit your teeth, take it on, but don't back down!" give this version a personal, conversational and challenging direction.
