"Invaders Must Die"
From Tardis Wiki, the free Doctor Who reference
"Invaders Must Die" by The Prodigy was used extra-diagetically in the final moments of the Class story Detained, leading into the Next Time trailer.
It plays over Andrea Quill's reveal to Charlie that she's had her arn removed, and now has her free will back, as well as her gun. The excerpt used is instrumental only.
The song's official music video stars Noel Clarke, who played Mickey Smith in Doctor Who.
