Southern University Marching Band 2015's take on the song that you're going to have screamed at you outside every pub after 12 this Christmas is balls to the wall nonsense but that's just what happens when you have at least 200 brass instruments belting out the chorus. We're sure Adele would approve. Not sure how she'd feel about the cheerleader dancing though.
