Being from this neck of the woods (south Wales) I have written some songs about its industrial heritage including mining. But I just couldn't bring myself to put ink to paper about Aberfan.
Not sure why? Because it was mostly children lost? (there have been plenty of children killed in mining disasters). Because it is too close to home (hasn't stopped me before)Because I worked many years after with a survivor of that day? (not sure)
I think it is probably fear of doing a dis-service to the many survivors and relatives of those lost. I think I could only do it by completing the song and then doing the rounds to those involved to get their blessing, or otherwise. So I understand some of the comment above. Far easier to write about something 200 years plus ago isn't it?
