There was a thread on " I know the feeling " a while back....the best description of the tune as far as I can remember went something like this.....Can you imagine a steam engine hurtling down a very steep hill uncontrolably at 100mph, while the driver does a wild evil uncontrolable laugh, at the same time stoking the engines boiler with more coal urging the steam engine to go faster....
Can't remember who put that up but it pretty much hits the nail on the thread.
Yep defo one of the many beautys that you used to play Alan
