The roughly three-minute-long first movement could be a self-sufficient pop song in its own right. “Suite: Judy Blue Eyes” opened their first self-titled album in 1969.
As the story goes, the all-star band Crosby, Stills and Nash was founded by Stills (then part of Buffalo Springfield), David Crosby (the Byrds) and Graham Nash (the Hollies) at either the home of Joni Mitchell or Mama Cass Elliot (the answer depends on which band member you’re talking to) when they started harmonizing together, most likely to this very song. Stephen Stills wrote the four-part medley about his impending breakup with Judy Collins, a well-known singer at the time. The title is, of course, a play on words.
