A fantastic track, one that makes the hair stand up on the back of the neck. Definitely one of my favourites, and I’m eternally disappointed there were no other versions recorded. A more up to date example of a similar approach would be Page and Plant’s cover of Crossroads, not as classic in my view as the infamous Cream version but good nonetheless.
Regarding TRB, I recall hearing this a few years back and thinking there were some similarities. All in the ringing chords I guess.
