From 1990, please enjoy the amusingly monikered Hindu Love Gods and their garage rock take on Prince's "Raspberry Beret."
That's Warren Zevon, obviously, with 3/4 of R.E.M. Recorded strictly for fun in 1988 during the sessions for Zevon's underrated Sentimental Hygiene album, but not released until two years later.
Incidentally, I'm aware that this one isn't particularly obscure, but fact is I just downloaded it for free and I'm feeling insufferably pleased with myself. So I thought I'd share.
In any case, if truth be told, I thought as covers go it was kind of lame, or at the very least disappointing, when it first came out. Now, it strikes me as thoroughly charming...
