U2 have returned to Paris to perform shows tonight (Dec. 6) and tomorrow (Dec. 7) after canceling their gigs due to the deadly massacre at the capital that left at least 128 dead.

A few weeks later, U2 have returned to perform at the AccorHotels Arena for both shows. Before their performances, the band conducted an interview with CNN and talked about a song that paid tribute to the people of Paris and addressed the terrorist attacks called "Streets of Surrender.”  In the clip above, Bono explains how the song came together:

“It’s funny, we don’t really write by order. It’s the strangest thing the way we write. It’s very odd. We are more like jazz people. We improvise a lot. We rarely set each other tasks. Sometimes it happens,” he says.

“I have a song that I started for an Italian singer called Zucchero and it’s called the ‘Streets of Surrender.’ ‘S.O.S.’ is the title,” he added, before reciting some of the lyrics.

The band hasn’t announced when the official version will be out, but you can expect it to be performed live to honor Paris and empower them after the tragedy they’ve endured.
