Mooh, you're right about Bonham. The drum part on Black Dog is probably the most brilliant in rock. Bonzo plays as if he is keeping beat to an entirely different song than the rest of the band is playing. At first it seems jarring, then like a tug of war between giant ogres, then everything smacks together in a perfect driving cohesion. Sure, Jimmy and Bob probably stole the lyrics to that one too. "I don't know, but I been told/ Big legged woman aint got no soul" doesn't sound like a lyric a couple of Brits would coin.
The drumming on When the Levee Breaks is also amazing. Apparently, Bonham set up his kit in the stair well of a large old English manor house while the drum microphones were hung over the third floor rail.
