The world's been waiting three years for 25, the follow-up to Adele's phenomenally successful 21 - and the day is finally here. To mark the release of her album - which will no doubt shoot to the top of the charts and dominate the airwaves for the next several months - she performs a special concert at the BBC, interspersed with excerpts from an interview with Graham Norton, peppered with her trademark wit throughout.
