The earliest known live tape of U2 performing together has been discovered. The band's 17-song opening set on August 11th, 1979 for another local group, the Stougers, features U2 performing live at Dublin, Ireland's Dandelion Market. Stougers guitarist Pete McCluskey told the U2 fans site ATU2: "I am pleased that I recorded the show, and hadn’t realized the significance of it and its place in history until quite recently."

Prior to the new discovery, the earliest U2 gig making the rounds was the quartet's October 22nd, 1979 show at the Cork Opera House.

Rolling Stone reported: "The Dandelion Market tape captures U2 at a pivotal point in their development. Songs like 'Out Of Control,' 'Stories For Boys," and 'Shadows And Tall Trees,' that would later appear on their 1980 debut Boy were just coming into focus. Early songs they’d later deem unworthy of release such as 'Cartoon World' and 'Street Mission' were still in the set, but most intriguing is the presence of 'In Your Hand" and "Concentration Cramp.'"

U2's setlist on August 11th, 1979 at Dublin’s Dandelion Market:

"Out Of Control"
"Speed Of Light"
"In Your Hand"
"The Fool"
"Concentration Cramp"
"Another Time Another Place"
"Stories For Boys"
"Shadows And Tall Trees"
"Cartoon World"
"Alone In The Light"

During U2's 2005 Rock Hall induction Bono revealed that in 1987 the FBI warned him not to perform one night, when the group was campaigning to establish Dr. Martin Luther King, Jr.'s birthday as a national holiday, because there had been credible threats against him. He refused the advice, even though he knew he might die at the show. When it came to the spoken third verse in "Pride (In The Name Of Love)," Bono said he found out just what he meant to one of his bandmates: "I close my eyes, and when I look up, I see Adam Clayton standing in front of me, holding his bass like only Adam Clayton can hold his bass. And y'know, there's people in this room who'd tell you they'd take a bullet for you, but Adam Clayton would've taken a bullet for me. And I guess that's what it's like to be in a truly great rock n' roll band."
