It's 1997. Thirteen-year-old Simon and his best friend Kyle can't open a fridge door without belting out a show tune. And his family is even more eccentric.
Mum Debbie (played by Olivia Colman) is a whirlwind of matriarchal warmth in killer heels. Dad Andy is a lovable Irish softy and avid wine maker and older sister Ashlene is a wannabe ghetto queen.
Then there's family lodger blind Aunty Hayley (Meera Syal) and lobotomised grandma Narg (gran backwards) who lost God and found a foul mouth.
