I play that one as well and find it sounds and grooves better if you play something similar to the 'killer shuffle' pattern where you drop the snare out on 1 and 3 and ghost the snare on either side of the the 2 and 4. Still sounds the same and is easier to play.. except it's not a shuffle of course, it's straight. Not sure if he really plays continuos 8ths on that.. I've heard that from another drummer but can't really tell the difference..I'm also playing Rock And Roll (Led Zep), trying to be faithful to the Bonham groove where he's riding 8th notes on the snare the whole time, accenting 2 and 4. It's not crazy fast, but it feels really strange at first playing the 8ths on the snare drum, so I've got some work to do on it.
Also key is playing 1/4s on loose hats so they sound like they are busier than they are.
Love his 'out of nowhere' cymbal crashes.. whenever I smack those people turn and smile!
