I think you had an audio hallucination... After a re-listen this morning, I still could not identify this Slipknot! before The Other One. There was noodling, space, boogie woogie, but no Slipknot! in earshot. Please give this another listen in a neutral environment (The power of suggestion is probably overwhelming at TXR), and try to find the Slipknot! Please find it...
I recognize your vivid imagination has been reflected in previous posts, and I don't want to see any damage to your credibility.
It's dead and over when close enough is good enough.
