Union' is the thirteenth album made by progressive Rock band Yes. This was their last release featuring all members of the new line-up (Jon Anderson, Chris Squire, Trevor Rabin, Alan White and Tony Kaye) and the ex-Yes members group (Anderson, Bruford, Wakeman and Steve Howe), hence the name 'Union'. Incredibly enough during the process of recording the album, all eight members do not play together at once.
