Ah yes indeed it was Roger, you beat me to it..with Marlon Brando in the lead..."we dont go anywhere man..we just go!" and a very nasty looking Lee Marvin as the chain swinging bad boy. It was a bit before my time but caught up with it later as the film was totally banned in Ireland for something like 25 years..and all us bike enthusiasts of course were dying to see it because of the motorbike content. It was interesting too, and I think Im remembering this right, in that it was much heralded that Brando rode a British TRIUMPH motorcycle rather than the American Harley.
Ah Phil errrgh a bit embarassing that picture but I like the bike lol!!
ps: Brian I took the three aspirin and a lie down as you suggested and Im much better now ..My throbbing has passed!
