YesYears is a 1991 video retrospective of the progressive rock group Yes covering the band's entire history from their 1969 debut album through their 1991 release Union. The video features interviews with the entire band, which, at the time of filming, featured eight members (Jon Anderson, Steve Howe, Trevor Rabin, Tony Kaye, Rick Wakeman, Chris Squire, Bill Bruford, and Alan White).

The story of yes is as controversial as their music. The twists and turns of band's career is now told for the first time in a series of exclusive interviews with yes members past and present for this definitive and fully authorised DVD documentary.
