Part of the scenery for "Sir Prancelot" was what is known as a 'scrim.' As in most pantomimes, there are 'cloths' which are painted canvas and the width of the stage, and the height from the stage floor to just about the height of the suspended bars on which hang any lighting. They are then suspended from ropes which go up into the 'flies' in what is called the 'grid', an arrangement of pullies from which the ropes which are used to haul up or down the cloths for scene changes. The 'scrim' was used for scene changes up-stage of it and because it was translucent whatever was lit behind it could be seen by the audience, but if the lights behind it were turned off, the audience would not be able to see anything up-stage. This scrim was lowered in order for us to do scene changes. As this was going on, a scene would be performed downstage, thus allowing us time to perform the scene change. I trust this is making some sort of sense. Anyway, on one occasion the lighting technician didn't remember to turn out the lights behind the scrim as we did the scene change so we were seen by the audience, and since they were mostly children in the audience, they began to shout out that we were in view, making the actor's life very difficult as you can imagine, attempting to continue with their scene with children shouting out! We had to remain stock-still until the lights were turned off up-stage so we could continue with the scene change.
On one occasion we were messing about on the fly floor. I expect something to do with it being the Christmas period, the result of doing perhaps three shows in a day and being over-active. General fooling around. Well, anyway, as a result my knee came into sharp contact with one of the cleats which were used to tie off the ropes (or 'hemps.') At exactly the right height for my knee and it really hurt. As a result, for a day or two, I could hardly walk without a certain amount of pain. That's what comes of tomfoolery and actually quite unprofessional, even though, on reflection, I say so myself looking back on it now. A fly floor can be quite a dangerous place if you don't know what you are doing. I still get a certain amount of pain from that knee even today, whenever the weather is cold, there's a sharp wind or damp in the air.
