 This section started off with footage of Michael Caine in The Italian Job counting down from five , whereupon the Reliant Regal from Only Fools and Horses exploded with Del Boy and Rodney jumping out dressed as Batman and Robin . Caine 's words , You were only supposed to blow the bloody doors off ! , echoed around the stadium . All the lorries had the newspaper removed and a colourful street party erupted , while Madness performed " Our House " . This was followed by the Massed Bands of the Household Division marching whilst playing Blur 's " Parklife " . Entering on rickshaws , the Pet Shop Boys performed their hit " West End Girls " , and then One Direction performed " What Makes You Beautiful " from the back of a lorry . Next there was another performance by Stomp .
