Advent Calendar 2023 Day 22: All Star Record Breakers, 1977

We've inducted the two most famous parts of this show before, the concrete doughnut mass tapdance and Kenneth Williams with the big horn (and also Sarah Greene's big moment from 1981, plus the inaugural and non-star 1972 Christmas show), but you don't get to see a full show of the Children's BBC team letting their collective hair down and dignity go. Notably the pair of standouts come within its first ten minutes - yeah, we thought you could only end with the tapdancers and Roy on the fountain, but ours is not to question why. Instead the bulk of the programme puts Roy at the centre of the life story and work of Hans Christian Andersen, casting Kenneth as the storyteller and the multi-talented glory of Castle backed by a gang of pro-am actors and singers including John Noakes, Peter Purves and Lesley Judd, John Craven and Lucy Mathen, Cheggers, Johnny Morris, Jan Hunt, Julie Stevens, Maggie Henderson and Noel Edmonds as an inchworm.
