Wigan piano teacher - 'This is what saved me'

When Alan Gregory from Wigan was a lad, he really wanted to learn to play the piano - but his family couldn't afford lessons. Over the years, he became self-taught and passed his music exams, and now he spends his time providing free and subsidised piano lessons to people in Scholes who would otherwise be unable to afford them. Joe McGrath visited some of his classes.
