On the subject of the songs themselves....

I'm open to correction but I seem to remember that Dave's turntable song came from a famous incident at Kirkby in Ashfield shed. Somebody on the footplate of an 8F 2-8-0 didn't spot that the track he was on didn't line up with the table and drove the engine into the well! There was a lot of cursing and head scratching before they got it out again. There is a photo somewhere, will see if it's on the web.

Mind you they're all mad up theer me duck.
