WATCH: All-Male A Cappella Group Flawlessly Covers ‘Lady Marmalade’

Popular a Capella group Out of the Blue, from Oxford University, has released a flawlessly sequined—fabulously glittery—cover of the iconic “Lady Marmalade” for our listening and viewing pleasure.

Not only is it an impressively produced and performed version of the song, but it serves a worthy purpose!

The guys have released the Labelle cover as a charity single to help sickly children and their families.

Proceeds will go to benefit the Helen & Douglas House, a nonprofit that offers hospice care for terminally ill children in the UK.

According to the original post accompanying the video, the guys actually got permission to shoot the film at the famous Moulin Rouge venue. So the cover serves up some authentically saucy entertainment.

See hot single in the video above.
