The singer and his bandmates cancelled plans to perform in the French capital the night after the 13 November (15) atrocities, which included a massacre at an Eagles of Death Metal show at the Bataclan theatre, where 89 gig-goers were killed.

U2 subsequently rescheduled the scrapped show, the first of two Paris gigs, for Sunday (06Dec15) and they reportedly invited Eagles of Death Metal to join them onstage as they returned to the city for the first time following the concert horror.

In an interview with CNN prior to the gig at the AccorHotels Arena, Bono and guitarist The Edge discussed their reasons for choosing to wrap up their world tour in the City of Light.

"We think of music as the sound of freedom," said The Edge. "We think rock and roll has a part to play, so going back to Paris to us is not just symbolic. I think we're actually starting the process of resistance, of defiance against this (terrorist) movement."

Bono then went on to reveal the tragedy had prompted him to pen a new song titled Streets of Surrender, which he had started writing for Italian singer and close pal, Zucchero.

Quoting some of the lyrics, he said, "Every man's got one city of liberty, for me it's Paris, I love it.

"Every time I get lost down these ancient streets, I find myself again. I didn't come here to fight you. I came down these streets of love and pride to surrender."

The Irish star also touches on the Syrian refugee crisis with a line in the song referencing a young boy whose body washed up on a Turkish beach earlier this year (15).
