Mike Knowles: I spent over 40 years working mainly in comics, along with TV, Radio, animation and gonzo-style journalism for a “top-of-the-shelf” magazine, along with odd spells as a digital artist. Finally, there were the three gruesome years writing gags for comedians (even though they begged me not to. But what did THEY know about humour), in which I was cruelly subjected to the thick fug of cigarette smoke that permeated the working men’s clubs.
