Bono has claimed that U2 have just had their 'best three weeks in the studio since 1979.'

The Irish rock icon told Ireland’s The Late Late Show last night that the band, who are currently working on their 13th studio album, are enjoying one of the most productive streaks of their career:

"There won't be a U2 album unless there's something really special. You just gotta go to that place. You gotta dig a deep well and see what you can pull up. We've been through many songs and there's some great stuff. I would say we had the best three weeks in the studio that we've had since, like, 1979. Three weeks is all it should take...."

The 52-year-old, who recently dismissed reports that he’s a billionaire, went onto admit that he and the rest of the group need to raise their game following the disappointing reaction to 2009’s 'No Line On The Horizon':

"As a band there's no sense of entitlement. I think they're very aware that U2's gotta do something very special to have a reason to exist right now, so that's what we're doing. We're song writing -- you know the process. But it's -- they're amazing men. They really are extraordinary. They really, really want it."
