"We actually put out a questionnaire to see who everyone was looking forward to seeing and the feedback for The Rubberbandits was just incredible," said students' union entertainments officer Darragh Genockey.
Over 7,000 tickets for the event sold out in a day and a half, despite fears that it wouldn't be popular.
"It's a rite of passage, really. It's like a mini-festival except everybody's there in black tie -- it's the most bizarre thing."
Other performers included Bell X1, Fight Like Apes, Jesse J and The Streets.
