She's been shaking her tailfeather across Europe on the Mrs Carter Tour over the past few months, but tonight Beyonce and her pals are teaming up to support Chime for Change, an organisation that aims to ensure that young girls and women across the globe have access to education, health care, and justice. The Beeb will be packing the best of the night's performances into one little hour-long package. Expect performances from the likes of Jennifer Lopez, Florence and The Machine, and Ellie Goulding.
