Duran Duran to play Olympics concert in Hyde Park
Soon-to-split boy band JLS are the latest headliners for a series of major outdoor shows in London's Hyde Park.
The group, who announced last month that they will call it a day after a farewell tour later in the year, will share a bill with The Beach Boys and The Saturdays.
They are to play the new festival Barclaycard Presents British Summer Time Hyde Park, performing at a family-friendly day of acts on Sunday July 7. The event also features performances of The Gruffalo and Horrible Histories stage shows.
Performers lined up for other days during the festival include The Rolling Stones, Bon Jovi and Sir Elton John. Jennifer Lopez and Lionel Richie were unveiled yesterday as the stars topping the bill at the finale concert on July 14.
Rob Hallett of promoter AEG Live said of the latest line-up: "I have always wanted to promote a show where you can take your kids and your parents. Junior can be enthralled with the Gruffalo and your daughter can scream at JLS while your parents dance around to The Beach Boys."
The Rolling Stones have added a second date in London's Hyde Park after the first sold out in a matter of minutes.
The veteran stars will play their extra concert on July 13, a week after they return to play the outdoor venue 44 years on from their famed free concert.
Tickets will go on sale on Friday at 9am, although Barclaycard Unwind customers can buy from Wednesday.
The Rolling Stones concert in Hyde Park sold out in just five minutes despite fan concerns over ticket prices.
The 65,000 tickets for the central London gig went within minutes of being put on general release this morning.
AEG Live promoter Rob Hallett said the response had been "incredible".
Tickets cost £95, although there were hospitality packages for sale at up to £299 but Mr Hallett said basic ticket - holders would not lose out.
The band will headline the Hyde Park gig in July - almost 44 years to the day they played a famous free concert in the central London park.
The band will also headline Glastonbury and play a north American tour this year.
The band were criticised over the price of tickets for their 50th anniversary gigs at the O2 last year when the face-value price of the tickets ranged from £95 to £375.
A "VIP hospitality"' ticket was priced at £950.

The Rolling Stones will return to Hyde Park this summer, 44 years after they first played there.
The concert on July 5th, 1969 was overshadowed by the death of founder member Brian Jones who had died two days earlier. Replacement guitarist Mick Taylor made his live debut at the concert.
Sir Mick Jagger has said he is looking forward to the Rolling Stones' concert in July:
– Sir Mick Jagger
"We had such a great time playing the five concerts last year, we want to keep it going. Hyde Park holds such great memories for us and we can't think of anywhere better to perform to our UK fans this summer."
The Rolling Stones will stage a concert at Hyde Park this summer, 44 years after they first performed at the venue. The show will take place on July 6th. Tickets go on sale to the general public on Friday.
Bon Jovi said they are looking forward to performing at Hyde Park as part of the Barclaycard British Summertime Festival which starts at the end of June. They added they were not concerned about noise restrictions or the British weather which caused problems at festivals last year.
Rock act Bon Jovi are to headline a new festival which will be staged in London's Hyde Park this summer. The Barclaycard British Summer Time event, promoted by AEG, has been set up in the park after rival promoters Live Nation Europe transferred their concerts to the Olympic Park.
There have been problems with concerts at Hyde Park - last year the sound was turned off at a Bruce Springsteen concert because it would have broken a curfew brought in to protect local residents from the noise.
However, Rob Hallett, president of International Touring for AEG Live, said: "It is fabulous that, as we begin to celebrate a decade of working together with Bon Jovi, we come together again to launch a reimagined series of shows at the iconic Hyde Park."
The A4202 Park Lane Southbound is closed between A40 Cumberland Gate (Marble Arch) and A4 Hyde Park Corner due to a rehearsal for the Olympic triathlon event.
Hyde Park Corner closures will be in place on all approaches until around 07:00. The ORN (Olympic Route Network) will also have changes during this time which could cause a delay for drivers in the area.
