It's always important to get the local topical references in, if you can!

I remember seeing Albert Modley in "Mother Goose" when I was about 10. The theatre suddenly had a power cut - complete blackness. Before the audience could panic or become scared, a stage hand came on with a torch which he put in front of his face, saying "Anyone got a shilling for the meter?" Brought the house down and saved the day with a joke or two until the fuse box was sorted out.

By gum, them were't days...
