Oxford University’s all-male a cappella group has another cracker for you.

Following the success of previous singles All I Want For Christmas Is You, Santa Baby and Sleigh Ride, the boys are back with another annual festive cover, which helps raise money for charity.

This time, they’re taking on Slade’s classic hit Merry Xmas Everybody, and the music video sees them at their mischievous best while they decorate trees, unwrap each other (literally), and even throw in a little disco dancing.

Proceeds from the single go to Helen & Douglas House, the world’s first children’s hospice who provide palliative, respite, end-of-life and bereavement care to children and their families.
