U2 BIGGEST TOUR EVER 2009 - North America in the Summer

THE secret is out! Today we reveal the inside details of U2's biggest ever world tour.

The rockers are set to return with a bang by with a European stadium tour this summer.

And they will enjoy a huge homecoming celebration with three nights at Croke Park.

We have learned the band has provisionally booked the GAA ground for July 24, 25 and 26.

All tickets are expected to sell out in record time when details are announced next month.

With the album No Line On The Horizon released next month and their single Get On Your Boots No1 in Ireland, U2 kick off their most ambitious tour at the end of June with two shows at Barcelona's Nou Camp stadium.

Then they head to Paris for mammoth shows at the Stade France on July 10 and 11.

Bono can crash at his home in St Tropez as he plays a week of live shows in sun-drenched Nice.

Berlin and Amsterdam have also been booked in with capacities of 70,000 for each gig.

Next up it's Wembley in London, Millennium Stadium Cardiff and City Of Manchester arena in August.

Then Bono, The Edge, Adam Clayton and Larry Mullen Jnr head to America where they will play a full stadium programme for the first time in 12 years.

In September they go to New York, Boston and Chicago before heading to Miami, California and San Francisco over the winter.

A source close to the band revealed last night: "They have avoided US stadiums for the past two tours as they were worried they wouldn't sell out.

"They obviously think demand is there and want to reclaim their spot as the world's No1 band."
