'It was inspired by a Burmese leader, Aung San Suu Kyi, and her struggle for free elections in Burma. She left the comfort of her home in Oxford, as an academic, and her family and her son and her husband, and went to do the right thing for her people. And it was just one of the great acts of courage in the 20th century. And it's continuing into the 21st century - she's been under house arrest for some time now, and people get, you know, we all get very worried about how she's doing. At first, I was writing it from the point of view of her family, or her son, you know, her husband, and then in the end I kept it a little abstract and just let it be a love song about somebody having to leave a relationship for the right reasons.'
