For 50 years he's been putting his youthful past behind him; or perhaps more accurately, brushing it under the floral patterned carpet. In the 1960s, he was a Mod, a regular visitor to Brighton on his mirrored-up Vespa scooter, ready for a rumble with the Rockers.
Back then, he was in Brighton to smash up deckchairs on the beach. These days he merely sits on them to take in the view. But the rebel in Henry never really went away. It was just brewing.
Recently bereaved, Henry has nobody to rein him in anymore. His aggravating daughter Cath (Anna Crilly) and her utterly ineffectual husband Jeremy (Amit Shah) aren't up to the job, and his best friend Charles (Bill Paterson) and charity shop owner Margaret (Anita Dobson) merely fan his flames.
So, with a growing sense of injustice about all the petty day-to-day bureaucracy and general nonsense he has to put up with, Henry is about to give the world a much-needed kick up the backside.
Adapted from his own cartoon strip 'The Rebel' in 'The Oldie' magazine, Andrew Birch has created an anarchic, anti-establishment pensioner on steroids for the 21st Century.
