Eric Bogle wrote "The Leaving of Nancy", about his mother who was crying as she was waving goodbye to him from the railway station platform as his train moved off on the day he emigrated to Australia from Scotland. I only moved a few hundred miles down to London in 1985 but my mum didn't stop crying for days and I have faithfully phoned her every Sunday since. And so every time I sing that song the tears start welling up and I have to stop - compose myself - then carry on, well done Eric, I bet there are hundreds of people who react similarly to that song for similar reasons.
