Eagles of Death Metal singer thanks Bono for his support
Eagles of Death Metal frontman Jesse Hughes was sent a phone with a note from Bono telling him to call his mother the day after the Paris terror attacks.
The US rock band were set to play at the Bataclan theatre when scores of their fans were gunned down in the November 13 atrocity.
Eighty-nine people were killed at the concert venue out of a total of 130 murdered in bars, cafes and restaurants in the unprecedented shootings.
The band made a surprise return to Paris when they joined U2 on stage for an encore earlier this month - and Hughes has hailed the Irish rockers for taking care of them.
He told Rolling Stone: "Bono knows that I'm a Christian, and he also knows I'm a mama's boy.
"The very next day (after the attack), a courier came with a phone that had a note that said: 'This is from Bono. Make sure you call your mom.' I thought that was awesome.
"It was the first time that I really got to talk to my mom without being in a police station, and that meant the whole world to me at that moment.
"Then Bono called because I needed advice. I felt like the best person to ask for advice on how to deal with this is someone who's rubbed elbows with world leaders. And he just prayed with me on the phone."
Talking about returning to the stage with U2, Hughes told the magazine: "U2 were trying to make sure we didn't have something in us killed.
"They would have accomplished their goal if they had just performed the song with us. They didn't have to give us the stage for the last song. And they did. They took care of us completely."
The California band escaped the carnage by hiding in a dressing room backstage in the Bataclan and later told how they want to return to Paris to finish their performance.
They have now called on fellow artists, irrespective of music genre, to cover their song I Love You All The Time.
They will donate all of the publishing income to guitarist Josh Homme's charity The Sweet Stuff Foundation.
The organisation is providing assistance to the families of the attack's victims.
