U2's Bono joins Bruce Springsteen on stage

- Bruce Springsteen's The River tour held another pretty epic surprise this weekend, with him inviting U2's Bono on stage at Dublin's Croke Park, Gigwise said.

The rock heroes came together to duet on 'Because The Night' - the classic Patti Smith song that Springsteen co-wrote. The pair had previously performed the track together at a 2003 E Street Band gig in Miami, and together with Smith herself at a 2009 Rock and Roll Hall of Fame 25th anniversary show in New York.

Springsteen's UK tour continues this week, culminating in a massive show at Wembley.
