When I was a wee thing,it was a family tradition to go to the Ipswich Rep Theatre for whatever panto was on, usually 3 familes of us together, and always the Boxing Day matinee, then back to each others' houses for a big tea.
Then when I went to medical school, we always did a Christmas Show, which was very much like pantomime and involved caricaturing all the hospital consultants. The show names were often puns on real pantomime names, e.g. "Salmonella" instead of "Cinderella", and "A Lad In Whitechapel" (work it out!) and of course we had a big muscular male Dame! Our producer had a penchant for Gilbert and Sullivan, so many of the songs used Sullivan's bouncy tunes.
Similar shows during my house jobs down in Devon, where the 2 male, bearded "Fairies" were Fairy Liquid and Fairy Nuff. And the sleeping princess was awoken by everyone shouting "Boo!" as loudly as they could! The consultants and their spouses got front row seats, but then regretted it when the 50 ml syringes were used to spray the audience! I was more involved with playing piano for these shows.
Oh those were the days!
Nowadays we're more likely to go to a ballet at Christmas, but these are often versions of well-known tales, such as "The Snowman" or "Hansel and Gretel".
