Dekay, your 'Smoke On The Water" is truly awesome.
I got such a kick out of that!
Personally, I am a big fan of The Bad Plus' covers - they've done everyone. I like Iron Man (Black Sabbath), Chariots of Fire (Vangelis), their live version of Tom Sawyer (Rush) is great, and Smells Like Teen Spirit (Nirvana) is one of their great songs. Youtubing is actually kind of hit-and-miss - there are some decent ones, but there are some so-so versions of the same songs, so if you don't like the version you see, you can look around for another.
And one other... Gretchen Wilson (fantastic pipes) did a cover of Barracuda with Alice in Chains a few years ago which is fantastic.
