A nice review of the U2's historic performance 29 years ago on July 13th.
"U2 formed in Dublin as teenagers in 1976. Between 1980 and 1985, they released four albums (Boy, October, War and The Unforgettable Fire).
On July 13th, 1985, seemingly every major rock act on Earth played the Live Aid concert for African famine relief, hosted primarily in Philadelphia's JFK Stadium and London's Wembley Stadium and broadcast to over a billion people worldwide. Backstage at Wembley, U2 met some of their heroes, including Pete Townshend, David Bowie, Paul McCartney and Muhammad Ali. Freddie Mercury flirted with Bono, who was previously unaware that the Queen singer was gay.
U2 hit the stage in London at 5:20 p.m. Greenwich Mean Time (12:20 p.m. on the East Coast of the States); they had a 20-minute slot between Bryan Adams and the Beach Boys (both performing in Philly). After being introduced by Jack Nicholson ("a group that's never had any problem saying how they feel"), U2 kicked off their set, which they intended to be three songs long, with 'Sunday Bloody Sunday.'"
Then Rolling Stone explains with details what happened in every minute of that performance and the reaction of the band and the consequences of the day to U2's career. Nothing really 'new' to us but it's good to remember
