Also! I just mentioned this in the terrible covers thread, but, Ozzy Osbourne put out a covers album a few years back (out of which, three songs are Lennon). It's mostly assorted classic rock, along the lines of Bowie, Beatles, Rolling Stones...it's fairly hit and miss, but!
He did an amazing version of Sunshine of Your Love on it. I don't really care much for the original (I think it's a great song, but then they got Eric Clapton to play on it), but this version is so much fucking heavier and awesome, I just love it. I have to go put this on now. Yes. Yes.
