I remember watching "Close the Coalhouse Door" at Leeds Playhouse when I was at university in the early 70's- a brilliant play. The best rendition of the tune itself is from the Wilsons - it's almost their theme song, and it makes the hair walk up the back of my head whenever I hear it. I have a vague memory that Alex Glasgow added the verse about the children in the coalhouse after Aberfan, and it wasn't in the original. Sorry to hear that he too has gone on (as they say in Dorset), Sam Sherry, Douglas Adams and Alex Glasgow - Definately not a good week.
