Wherein young Neil Young, still just a member of Buffalo Springfield, hears the Beatles Sergeant Pepper’s and responds with an epic piece of something or other. It starts with a live snatch of one of the other songs from the album, slips sideways into various surreal reflections on this-that-other things, finishes up with some honky-tonk piano that just sort of fades away into a heartbeat. It’s all definitely about something, which in 1967 was all you really needed.
