Re: John Bonham
That looks like a pretty sound transcription. Really the best way of counting it is to feel it, I can't think of a strict way of doing it personally but then again theory never has been my strong point.
For an interesting variation on the introduction, I play the off-beat snare hits as bass notes so it goes something like this:
(S) = Snare (B) = Bass
Something along those lines. It's too late to transcribe it properly but it sounds good if your right foot can keep up.
EDIT: StickTrick I entirely and utterly agree with you. Music is not a competition, stop making it one. BTTM I remember you used to do this all the time and it really got on my nerves.
