Remember when that Oxford a cappella group's version of 'Hips Don't Lie' went viral? Well, they're back, and this time they've got a Christmas single.
The all-male Oxford student a cappella group, Out Of The Blue, have released their cover of 'All I Want For Christmas Is You' (with a little excerpt from 'Santa Claus Is Coming To Town') in aid of children's hospice Helen & Douglas House.
There's almost too much grinning and good-natured tomfoolery to cope with, but it's all for a good cause.
