They appeared onstage yesterday during a performance by U2, who were playing the last of four concerts in Paris, the last two of which had been postponed when France announced a state of emergency following the attacks that killed 130 in total.
U2 frontman Bono told the audience they said he wanted to introduce "some people whose lives will forever be a part of this city of Paris. These are our brothers. Our fellow troubadours. They were robbed of their stage three weeks ago, and we would like to offer them ours tonight."
The two bands then played the Patti Smith song "People Have the Power."
The Eagles of Death Metal frontman Jesse Hughes told U2 and the crowd, "We love you too, so much for giving us this opportunity. I look around and what do I see, nos amis, our friends. I f---ing love you guys so hard, and I will never stop rocking and rolling.
