"True Love Waits" is a song by the English alternative rock band Radiohead.
 Its lyrics address love, ageing, and abandonment.
 Radiohead first performed "True Love Waits" in 1995, and singer Thom Yorke performed it alone on acoustic guitar or Rhodes piano numerous times in the following years.
 The band and their producer Nigel Godrich attempted to record it for their albums "OK Computer" (1997), "Kid A" (2000) and "Amnesiac" (2001), but struggled to find an arrangement that satisfied them, and it became one of their most famous unreleased songs.
 A live recording from the "Amnesiac" tour was released on "" (2001).

 Thom Yorke had performed an early version of the song with the band Headless Chickens while he was a student at University of Exeter in the late 1980s.
 Radiohead later recorded a studio version of "High and Dry" during the sessions which produced the song "Pop Is Dead" in 1993, but the band dismissed it as a "Rod Stewart song".
 During recording sessions for "The Bends," the band's demo recording of the song was rediscovered and remastered for inclusion on the album, as it was felt that it worked well with the rest of the album's music.
 In a 2007 interview with Pitchfork Media, Yorke stated that he did not like the song, saying "It's not bad... it's very bad".
 He also stated that he had been pressured into including the song on "The Bends".
