Have you ever wondered what introverts really get up to? Is it really a kind of neurodivergence? Does it actually exist at all? The Mirthful Japes of Cliff Ditheroe is the story of the author, as he navigated the choppy seas of childhood, young adulthood and middle-age, during the 'sixties, 'seventies, 'eighties and beyond, making many a false start on the way. Travel with him on a good-natured journey involving a strict, Catholic public school and the seamier side of 'eighties club culture, through interstellar space and beyond, on a bicycle named Beryl and in a Triumph Herald with an attitude problem. Ride the goblin motorway with the four heavy-metal aid bikers of the apocalypse, while being chased by a deranged boxing monk. This is a tale about beards, bagpipes and banjos; of marijuana, LSD and vol au vents... and music, music everywhere! Prepare for accounts of bizarre occult practices in the heart of rural Suffolk, brain damage and forklift carnage, all while wearing deeply embarrassing clobber (possibly involving Lycra!) Best of all, every word is true. Mostly... And there is an accordion!
