Mary Berry was the star of the show as she flicked the switch on Amersham's Christmas lights on Saturday evening. 

The national treasure led crowds in an impromptu rendition of Away in a Manger with pupils from Woodside School and Amersham Band while celebrating the town's festive lights switch-on on December 9. 

Mary's appearance formed part of the Amersham Christmas Festival, which saw Sycamore Road transformed into a Christmas market with a range of attractions including an entertainment stage, fun fair and food stalls.
