The song is the third track on Neil Young\'s album "After the Gold Rush". The song was supposedly written for Graham Nash after Nash\'s split from Joni Mitchell, though Young in interviews has been somewhat tentative in admitting or remembering this. Released as a single in October 1970, it became Young\'s first top 40 hit as a solo artist, peaking at number 33 in the U.S. The single was issued with a Crazy Horse version of "Birds" (rather than the solo piano version of the album) on the B-side, apparently accidentally. The song is praised as a "seemingly simple song which display[s] considerable attention to detail in the deployment of instruments."']}}]}]
