From 1967, please enjoy Atlanta, GA psych-garage rockers The Fly-Bi-Nites and their totally obscure until two weeks ago non-smash hit "Found Love."
In case you're wondering why I bring this up, it was the song playing on the soundtrack to the recent Mad Men episode where Don freaks out at an L.A. hippie pool party after smoking some particularly potent hashish.
As you can hear, it sounds like The Seeds instrumentally, but the vocals are rather more like The Association. I'm guessing this particular stylistic mash-up accounts for it not having been a chart-topper.
In any case, god only knows who connected with the show discovered it or how.
