I remember that one as well, and yes like you Pete I was on the floor laughing. The reg numbers were nothing to do with me at all though.
I have a whole host of Johnny Weston stories, but it would be unfair of me to pick on him that way, so here's one at my expense.
Years ago at one of the Bretby niters I was asked if I planned my spot, and I rather blithely answered "No I just play whatever comes to hand, I'd play the spoons if I had any". A month later, just after I started my spot someone appeared with a plastic spoon and asked me to play it, then another one, then another, and another. Eventually people stopped coming up with spoons, they had knives, and forks, and even serviettes. By the end of my spot I must have had nearly sixty plastic utensils and serviettes and was helpless with laughter.
Well done to Gaye Kidson for setting it all up. I love the ones like that where a bit of planning goes into it
