On Monday 11th March, singers from Some Voices choir assembled bright and early at the BBC Studios to sing presenter Mollie King off on her Pedal Power Challenge for Comic Relief, live on the Radio 1 Breakfast Show with Greg James.

The choir, led by Alice Morgan and with acoustic guitar by Owen Roberts, sang an original arrangement of ‘All Fired Up’ by Mollie’s band, The Saturdays. Mollie was seen cheering and dancing along to the track, before the klaxon sounded and she began her cycling challenge.

Mollie King’s Pedal Power for Red Nose Day on Radio 1 saw Mollie cycling for five exhausting days 500km from London to Hull, a place close to Mollie’s heart. Mollie has so far raised an incredible £1.1 million for Comic Relief.
