Gloria Gaynor: Surviving and thriving, 40 years on

Forty years after recording one of the most enduring songs of all time, the queen of disco Gloria Gaynor speaks to Eve Jackson about how "I Will Survive" became her personal mantra while facing her own hardships of abuse, divorce and paralysis. She talks about the book she wrote, gathering the stories of people empowered by her hit song, and reminisces about how it became the unofficial anthem for the French football team when they won the 1998 football World Cup.
