Hi All
Dave, the fine art thing sounds interesting - may have to work on that one

John, yes I know of Tony, I replaced him when he retired !
Bev, now you have a good point there - Im sure they would do a long kiss for you, but you are quite right a quick peck on the cheek is something to catch and I don't envy your job.
There again if you come to my lecture you will see some high speed photography of gas Propane cylinders exploding and also what an industrial firework can do to a Mkiii Ford Escort Car.

Best wishes to you all
Chris
