I found myself curious as to who else has covered this song, so I looked it up. I discovered a nifty little site that tells you who has covered a particular artist, and who that artist has covered. Take a looksee:
I had no idea that Pearl Jam covered Floyd, if anybody has that and wants to send it to me via aim (wikid garden is my screen name) I will love you forever! Also, Metallica apparently covered AIC's "Man in the Box"? AWESOME. I'm a huge Alice in Chains and Metallica fan and I never knew that.
