1 September, 2013: Lady Gaga fans queued for almost 24 hours (in some cases) to make sure they got into the Camden Roundhouse on the first night of this year's iTunes Festival.

Lady Gaga made her first live performance on the opening night of the iTunes Festival (1 September, 2013) since cancelling the last leg of her Born This Way ball tour earlier in 2013 to undergo hip surgery. The star has promised to perform an hour of all new material at her gig at the Camden Roundhouse - so anyone turning up expecting a set packed out with hits including 'Edge Of Glory' or 'Poker Face' might find themselves disappointed.

Lady Gaga's iTunes gig is really one for fans only, and we headed down to Camden Roundhouse today to check out London's most committed Little Monsters - some of whom had camped out in Camden for nearly 24 hours to get a glimpse of their pop idol.
