Checking out the second Rusty video, I just want to point out that the first line of the verse, when the guitars walk down to D, the bass actually plays A and Bb, the D being the third of the Bb chord. I have to run, but I can't wait to see the rest of it! Thanks for doing it!
I had the whole 70s version worked out for the beginning of Slipknot (up to the jam and also out of the jam), but my band keeps playing the 80s version, so it's a little lost at this point, but maybe I can work it up again and post a video.
Not a tab guy, but if I was really motivated, I would put it together in standard notation.
