From the deluxe CD reissue of their 1967 masterpiece Younger Than Yesterday (and the B-side of their epochal flop single "Lady Friend"), please enjoy The Byrds' "Old John Robertson."
Ah, those guitars, those harmonies, that genuinely poignant lyric, and that phase-shifted string quartet in the break...it all adds up to absolutely gorgeous pop perfection. And brought in at just under two minutes, which makes it even more remarkable.
You can download it HERE. As always, if the authorization has expired by the time you get there, just e-mail me blah blah blah.
And incidentally, after the song ends keep listening for another ten seconds or so until the hidden bonus track begins. It's a three-guitar instrumental -- Roger McGuinn, Chris Hillman and David Crosby, 'natch -- with all concerned apparently jamming away on a lovely, somewhat contemplative folkie riff, not quite raga-ish but vaguely mid-Eastern sounding.
The first time I noticed it on the CD, I remember thinking "Nice, but what's the point?" A few months later, I bumped into Bob Irwin, who produced the reissue, and asked him about it. Turns out that it was played backwards for the guitar effects track on "Mind Gardens," the David Crosby song that everybody but Crosby has since conceded is the one bummer on Younger Than Yesterday.
In any event, when you hear it, you'll realize that the Byrds didn't just invent folk rock, jazz rock and country rock: They also invented New Age.
Don't hold it against them, obviously.
