Home Advent Calendar 2017 Day 19: Wogan In Pantoland

What panto is that opening routine from, then? From 1988 a roll-call of appropriate guests and Jim Davidson file on, do their routines, then run through their pantomime anecdotes - Hudd, Biggins and Cribbins as dames, Barbara Windsor as the fairy, Dana as Snow White, Little & Large as something or other, and at the end a Cinderella whose identity seems to be a genuine surprise to Tel, unlike the identity of the group song that ends matters.
