"Roundabout" is a song by the English progressive rock band Yes from their fourth studio album Fragile, released in November 1971.

The song originated in March 1971 when the band were on tour promoting The Yes Album (1971), travelling from Aberdeen to Glasgow after a gig in Aviemore, Scotland.

'"[7] He began to write the song's lyrics in his notebook in a free-form style with minimal edits: "I just loved how words sounded when I put them together.

"[8] Within 24 hours, the band had arrived back home in London where Anderson reunited with his then wife Jennifer, which inspired the song's lyric "Twenty-four before my love, you'll see, I'll be there with you".

Early into the sessions, keyboardist Tony Kaye was fired from the group over his lack of interest in learning more keyboards to expand the band's sound, and was replaced by Rick Wakeman.

"[7] In 1994, former Yes guitarist Peter Banks whom Howe replaced in 1970, claimed he had come up with the song's main riff several years prior to the band recording it.

[11] In its original form, the song began with the acoustic guitar, which Howe played on a 1953 Martin 00–18, but the group soon thought a more dramatic opening was needed.

Offord recalled a considerable amount of time was spent to get it right in the studio because it involved a lengthy process of picking the right voicings to use, and editing them correctly.

Some changes include an abridged instrumental intro, which forgoes the 40 second nylon string passage played by Howe and skips the second hearing of the bass riff.

[10] Record World said that "If, as it seems, the time has come to say yes to Yes, then this drastically-chopped cut pulled from the new Fragile album will succeed mightily" and praised the harmonies.

In the 2003 film School of Rock, Dewey Finn recommends the song and its keyboard solo to one of his students, saying that "it will blow the classical music out your butt".

The song is referenced in the Season 4 episode of The Venture Bros. "Perchance to Dean", in which a similar melody is played like the ending to the actual track.

[20] The usage of "Roundabout" within JoJo's Bizarre Adventure has additionally led to both it and the series' "To Be Continued" insert becoming a collective internet meme, in which videos, most notably of events that happen in real life, feature the song's introductory acoustic guitar riff before coinciding with the "To Be Continued" insert, typically freeze-framing at a point where an accident, injury or death seems imminent.

The song was performed by keyboardist Rick Wakeman, vocalist Jon Anderson, guitarists Steve Howe and Trevor Rabin, and drummer Alan White with Rush bassist Geddy Lee filling in for Chris Squire, who died in 2015.
