"They were robbed of their stage three weeks ago and we would like to offer them ours tonight," Bono told the crowd on Monday night.
The City of Light just got a little brighter.
U2 welcomed Eagles of Death Metal with open arms to their stage at the AccorHotels Arena in Paris, France on Monday night. The surprise appearance and return to the city came less than a month after 90 people were killed in a deadly attack during an Eagles of Death Metal show at the Bataclan venue. A total of 130 people were killed in attacks throughout the city.

"We want to offer our heartfelt thanks and appreciation for everything our brothers in @u2 did for us in the aftermath of the November 13 attacks," EODM Instagrammed following the show. "They reminded us that the bad guys never take a day off, and therefore we rock 'n rollers cannot either …and we never will. We are incredibly grateful to U2 for providing us the opportunity to return to Paris so quickly, and to share in the healing power of rock 'n roll with so many of the beautiful people – nos amis – of this great city."
Continuing to express their gratitude, the caption continued, "Thank you to Bono, The Edge, Larry and Adam, thank you to their wonderful management, thank you to France, and thank you to everyone in the world who continues to prove that love, joy, and music will always overcome terror and evil. We look forward to fighting the good fight on many more fronts very soon, especially when we pick up our tour in 2016. See you again in February, Paris."

U2 responded via Twitter, writing: "@EODMofficial @Bruno_Fraioli We lent you our stage, but you owned it. Thank YOU @EODMofficial #U2forParis."
Bono and the band was to perform in the 16,000-seat arena on Nov. 14 and 15 but rescheduled after the terrorist attacks.
"Terrorism relies on people being terrorized, and we were not going to be," Bono, who has a home in France, told The New York Times ahead of the shows, the second night of which aired on HBO. "We felt the biggest and the only real contribution we can make at moment like that is to honor the people of Paris, who brought us the concept of liberté, égalité, fraternité."
