Fight Test (US version) is an EP by The Flaming Lips featuring the song of the same name, released on Warner Bros. Records in 2003, shortly after the release of Yoshimi Battles the Pink Robots that same year. The single version of the "Fight Test" release was released in June 23, 2003, peaking at #28 in the UK Singles Chart It is an enhanced CD, and it contains covers of Radiohead's "Knives Out", Kylie Minogue's "Can't Get You out of My Head" and Beck's "The Golden Age". In addition, the Fight Test EP includes two as-yet unreleased original songs. The UK version was a normal CD single release, which also featured some previously unreleased songs. The song "Fight Test" is musically very similar to Cat Stevens's 1970 song "Father and Son." Stevens, now Yusuf Islam, is receiving royalties following a relatively uncontentious settlement. The band's frontman, Wayne Coyne, claims that he was unaware of the songs' similarities until producer Dave Fridmann pointed them out. The opening of "Fight Test" ("The test begins...now") was sampled from one of the sync tests from the Flaming Lips' own Boombox Experiments.
