Advent Calendar 2019 Day 16: So You Think You Know About Christmas?, 1980

So You Think...? was a panel quiz show strand that ran every so often in one-offs between 1965 and 1984, each based on a theme set by Cliff Michelmore at his irreverently masterish best, with scoresheets to play along at home provided by Radio Times. Oddly its only festive special was co-hosted by Magnus Magnusson, with eclectic studio teams Tim Rice, harpist Mary O'Hara and Paul Daniels against Arthur Askey, Susan Hampshire and Basil Brush, who Cliff clearly tires of early. Remember to give yourself fifteen points at home.
