Around 160,000 fans gathered at Croke Park over this weekend to see Bruce Springsteen and his E Street Band. Last night's gig was extra special as Bono joined The Boss to stage for a surprise duet of 'Because The Night'.
The U2 frontman had been spotted arriving with his bandmates Larry Mullen and the Edge earlier in the evening.

U2 and Bruce Springsteen have teamed up a couple of times over the years. Bruce joined the band on stage in New York’s Madison Square Garden in August 2015.
