Here they go again! But Dawn French and Jennifer Saunders will perform as a double act for the last time on Red Nose Day.
It's wigs and dungarees all round for their final performance - a parody of the movie musical Mamma Mia. It's all in aid of Comic Relief which helps disadvantaged people in Africa and the UK.
Also featuring in the sketch are Philip Glenister, Sienna Miller, Alan Carr and Matt Lucas. Watch French and Saunders sashay into Red Nose Day on Friday 13 March from 7pm, BBC One.
