I saw him once during the Festival in Edinburgh, even though I barely remember it as I was pissed as newt - not unusual for me during the Festival.
I had a really bizarre moment in 2001 when I was given a Bill Hicks video, and he did this routine about President Bush involving the world in a war in Iraq - I thought it was wonderfully current and edgy, till I did the inevitable double take, it was recorded a decade earlier, and the Bush was GH, not GW.
I still dig out my recordings, they're still as perfectly pitched now as the first time I heard them.
My father introduced me to Lenny Bruce, Bill picked up his ball and ran with it. So many comedians try to emulate his anger, but never manage to blend in the satire, wit and most importantly humility, that tempered Bill's rants.
