Appropriately, “Suite: Judy Blue Eyes” was the first song that appeared on Crosby, Stills and Nash’s first album, and was also the first song they performed at Woodstock. While not their biggest hit – perhaps because of its length (7:24) – the suite is a showcase for the group’s signature strong point: harmonies. “The three-part vocal blend was f---ing fantastic,” says Graham Nash. The song itself was written by Stephen Stills, who plays most of the instruments on the recorded version, as a broken-hearted love ballad for his ex-girlfriend, folk singer Judy Collins. Stills stitched different lyrics from different notebooks together, hence the “suite.”
