The Oxford all male a capella group ‘Out of the Blue’ unleash their inner queens in their version of ‘Lady Marmalade’.

The classic Patti LaBelle track was has been covered endlessly by a number of divas – from All Saints to the Moulin Rouge super-collab. But we have to hand it to these boys for turning the sass up to 90 and making this video for charity.

Nice one, guys!
