THEY once stopped traffic by performing on an LA rooftop.
But U2 were back on the roof in New York recently where their audience was made up of patrons of a nearby Irish bar.
Unlike in 1987, when they filmed the Grammy-winning video for song Where The Streets Have No Name, their latest high-rise jam was a closed set.
The band performed an acoustic version of Sunday Bloody Sunday for a series of videos for Bono's One charity, where artists sing protests songs that changed the world.
The performance took place on the roof of New York's Electric Ladyland studios where U2 are currently recording their latest album, and featured bass-player Adam Clayton on piano.
However Bono & Co were said to be amazed when they stopped playing to receive cheers of "Ole Ole Ole" from the patrons of a local upmarket Irish bar who had gathered on an adjoining rooftop.
"Bono was amazed when he heard the sound of the Irish voices coming over.
"He didn't know there was an Irish bar across the street and promised to stop by but couldn't that night because he had some other event to attend uptown that night," Mayoman George Garrity, owner of the upmarket PourGeorge pub restaurant in Greenwhich Village, told the Herald.
The version of Sunday Bloody Sunday was dedicated by Bono to fans in Iran, who have adopted the song.
"This is a song written about the Troubles in Northern Ireland but means a lot to people in conflict zones," said Bono before the performance,which is being made available across Iran through facebook and YouTube.
