Before she became one of the best-selling musicians of all time, Shania Twain worked for the family tree-planting business, singing for tips in lumberjack bars to help make ends meet. Stephen Smith charts the rise of a hard-up Canadian country girl, from a violent family home, to a country-pop crossover superstar.

This year's Glastonbury 'Legends' slot will be the first time some will have seen or heard from Shania in decades - we hear about the disease that robbed her of her voice at the peak of her powers in the early 2000s and, along with a devastating divorce, led to a 15-year gap between albums.
