Before everyone goes back to work on Monday (boo - oh, sorry, yay, 'cos I ain't), here's one last Christmas treat. Put off the festive detox for just a few minutes. Last Christmas, the website dedicated to Wham!'s song from 1984, has now featured up to 390 covers of said ditty. And this year, to save you from tears, they have a special visual cover version. The acapella band Bliss have recreated the video in Saas-Fee, the original Swiss location, and despite the ropey barnets, have done it brilliantly.
