I guess he was a sort of Jack Kerrouac for the post-beat generation. I read Fear and Loathing at school in about 1981 and was mightily influenced by it. Along with Robert Perzig's Zen and the Art, it made me realise there was a great big world beyond the walls of a provincial grammar school, with plenty of high jinks to be had along the way.
FWIW, another great avant-garde exponent passed away recently (drowned in the Thames whilst pissed). Malcolm Hardee was the kingmaker behind the alternative comedy movement in the 1980's. He brought to fame Sayle, Mayall, Authur Smith and a host of others. Along with a friend, he broke into London Zoo one night, shook hands with a gorilla and went back to the pub. He was also responsible for smashing up Freddie Mercury's 40th birthday cake, which had cost a reported £4,000. After his funeral, Arthur Smith described Hardee as "a total shite".
As Mick Channon once famously said, "There's no characters left in the game no more".
RIP both.
