He made a film called 'The Endless Summer', which was a pioneering bit of surf travelogue for it's time. It's a bit tame and cheesy by today's standards, but still a great watch even if you're not into surfing. I think the whole thing is on youtube to watch.
Yeh, haven't seen any speculation yet though. Hope the guys alright. It's a pretty massive thing to cancel a tour that far ahead.
