Five albums, seven UK number one singles, ten million records sold worldwide and ten years in the industry.

McFly are a mainstream pop group who came through the system properly – not via the fast-track talent show route – and they play their own instruments.

A band with that track record is difficult to criticise.

Thousands packed into the Brighton Centre to sing along to the tracks that have made McFly the success they are today. Obviously, Five Colours In Her Hair, All About You and Heart Never Lies all rang out to please the crowd of mainly teenage girls.

But there was a twist. A piano and guitar duet from Tom Fletcher and Danny Jones hushed the screeching, pre-pubescent crowd to allow older audience members to appreciate that McFly really are talented musicians.

As familiar as their sound has become, you can’t criticise them for standing still either, with new songs drawing on dance influences and – for McFly – some heavy rock.

Maybe the problem is people look to poke holes in a successful band whose target audience is schoolchildren.

But they also act as a guilty pleasure for older men and women who simply enjoy a catchy, cheesy tune.
