Bono reveals to Stephen Colbert how U2 got one of its first big breaks

U2 seemingly got one of its first big breaks in mysterious ways.

The band’s lead singer Bono joined “The Late Show With Stephen Colbert” Thursday night and revealed how the band gained exposure by passing off The Ramones’ “Glad to See You Go” as their own.

When a prominent television producer visited Mount Temple Comprehensive School, where Bono, the Edge, Adam Clayton and Larry Mullen Jr. attended high school, the rock group played to the tune of a lie when asked to perform an original song.

“We had a big TV producer, a big cheese, come into our high school, and we were gonna get our break and get on the national telly,” Bono said. “There was a knock on the door … and we’re like ‘f–k.’ What are we gonna do?

“He walks in,” the 62-year-old singer continued. “‘So you write your own songs … Could you play me one?’”

After exchanging glances, the band busted out The Ramones’ 1977 hit, claiming it to be an original piece.

“That’s improvisation, too,” Bono joked.

U2 booked its first television performance in 1978 on RTÉ’s “Youngline” program.

The rocker also performed during the late-night slot, singing “With or Without You” while promoting his new book, “Surrender: 40 Songs, One Story.”

Bono, who’s real name is Paul David Hewson, opened his book tour at the Beacon Theatre in Manhattan on Wednesday, sharing life stories and songs to thousands of fans.

He will visit Boston’s Orpheum Theatre tonight before stopping in Toronto Sunday for another show.
