U2 have planned a surprise for fans at this weekend’s Super Bowl in America to promote their new single and raise money for the charity RED.
In an interview with USA Today, Bono said: "We’re taking all the energy around the Super Bowl and interest in what U2′s doing and flipping it into the fight against HIV AIDS."
One of the high-profile ads which will run during the game sees Bank America team up with the RED charity, which campaigns to eradicate AIDS, malaria and TB.
The ad will feature U2 performing their new single, Invisible and in addition as a thank you to fans who have supported RED, the ad will lead fans to a free iTunes download of the track.
Bono revealed that the band mulled over a couple of different ideas as to how they can thank supporters: "One plan was for us to go knocking on doors in the middle of America, thanking people for saving lives.
"But a couple of band members thought that might seem self-aggrandizing."
He added that he was "amazed" when the rest of the group agreed to give Invisible away for free.
"They don’t like to talk about it, but they gave $11 million of [U2's] last tour to (RED). They’re big supporters. And I’m very proud of them for this."
However despite reports to the contrary, this isn’t the debut single from the band’s anticipated new album, as Bono explained: "We have another song we’re excited about to kick off the album.
"This is just sort of a sneak preview — to remind people we exist," adding that "it’s the first one we finished" and he said that they will be working on the album "for a couple of months."
"We want it to come out this summer, but you don’t want to let anyone down."
