Re: John Bonham
Yeah he's pedaling 8ths on his hi-hat and also playing 8ths on a cowbell as the first note of the triplet with the stuttering bass drum notes in between.
There is no official live release of 'Good Times Bad Times.' From the bootleg sites that I've looked at, it does appear that they played if a very few times live in early '69 before they had any Zep II material to play, but those boots are extremely rare and probably not very good sound quality.
I know...I'd kill to hear a live version of Good Times from a young Zeppelin too. Bonzo would be out of his mind in that performance.
