'Baby Got Back' is one of those songs that you don't realise you know all the words to until it's 2am and you're standing on a bar stool screaming at the top of your lungs along with the track.

And you're not the only one, as Sir Mix-A-Lot proves as he performs the 1992 hit on stage with a whole host of very enthusiastic women and the Seattle Symphony Orchestra. We can guarantee that you've never heard the song like this before.
