BBC Comedy and BBC Scotland have commissioned Happy Tramp North to produce Only Child, a brand-new sitcom starring Greg McHugh (The A Word, Fresh Meat) as only child and budding author Richard, who travels back to his family home in North East Scotland to look after his aging and wilful dad Ken, played by Gregor Fisher (Rab C Nesbitt, Love Actually, The Cockfields), as he slips into ever more eccentric and erratic behaviour.
