Work Advent Calendar 2017 Day 19: Blue Peter, 1987

It's Christmas Eve and the Caron, Yvette and Mark team are proving that there's nothing so comfortingly repetitive as the format of the last BP before Christmas - final candle on the advent crown, cards from viewers, presents for the pets, big leap on the appeal totaliser, "last minute" make, crib, hundreds of kids in choirs, Chalk Farm Salvation Army band, big silver version of the ship at the end. To prove that it wasn't just the Richard Marson era where self-indulgence was allowed its head however, there's a Hollywood song and dance routine worked in too.
