They are a guitar-playing four-piece who combine good looks with catchy pop hits.

Boy band McFly are the latest act to be announced for Freedom Festival 2010.

The two-day event takes place across Friday, September 10 and Saturday, September 11.

Diana Vickers, Fyfe Dangerfield and Roll Deep are among the well-known performers already lined-up to sing alongside McFly on the Viking FM Stage at Humber Quays.

McFly are making a comeback with new single Party Girl two years after they split from their record label and decided to go their own way.

Harry, Tom, Dougie and Danny, recently showed off a slick new look by posing naked for a gay magazine.

They are rumoured to have added an R'n'B edge to their music, but fans will be hoping they play some of their previous chart-topping hits.

These include All About You, Obviously and Five Colours in Her Hair.

More announcements about the entertainment lined-up for the Freedom Festival will be made later this week.

This includes the Friday night programming and details of an unusual third stage in Freedom Gardens.

McFly's inclusion follows the news Mercury Prize nominees Foals will headline the Freedom Stage in Queens Gardens, which will be renamed Freedom Gardens for the weekend.

The band will be joined by the Bikini Beach Band, the Warren Acoustic Sessions, Creative Voice, Hot Gospel and the Nyanga Project on the main stage, located at the Hull College end of the gardens.

Councillor John Robinson, Hull City Council portfolio holder for image and culture, said he was delighted Mcfly had been added to the list of acts.

He said: "Freedom aims to cater for a range of tastes as part of its line-up – from pop on the Marina to the eclectic line-up in Freedom Gardens, as well as bringing new cultural experiences to the city and something for all ages.

"We are delighted to have attracted another household name to the festival and hope that McFly will enjoy being part of the Freedom experience in Hull."

Janet Reuben, chief executive of Visit Hull and East Yorkshire, said the weekend would be "unmissable".

She said: "The quality and variety of performances coming to this year's Freedom makes the event truly unmissable.

"The very best in live arts, dance and music will be combining to provide a cultural extravaganza in Hull this September."

There will be two viewing areas for disabled audience members at the festival.

One will be adjacent to Humber Quays One, with views to the stage and the other is located on the east side of the Marina – part of the family viewing area with views of a big screen.

People wishing to sign up to the guest list for the first area should email helen.thackeray@hullcc.gov.uk or call (01482) 613500 as soon as possible to avoid disappointment.

There will be one wheelchair space and two companions available per request.
