Incredibly down to earth guy too. I was fortunate enough in the past to play maybe a half dozen shows with Origin between 1998 and 2002. Just being able to talk drums with someone who is as knowledgeable as John was great, he had no ego and was more than happy to share insight and technique. Not something that can be said about everyone.
Arky, the double strokes he uses with his feet are all bounce. I haven't spent much time with learning it, I do a modified swivel, it works for me but honestly I don't need to go that fast anymore.
Here is a good video where you can see him switch between singles and doubles with his feet. It is at like 0:32 http://www.youtube.com/watch?v=0x8BT4-uxF4
The title of the song is The Burner.
Watching John play live is a MUST for any fan of drumming. You can't help but smile and giggle like a 5 year old girl.
