And he's described the Irish band's hospitality when he took part in their own Paris show as the best way to get over his fear of returning. EODM were on stage when 89 people were killed at the Bataclan venue last month. They guested with U2 just weeks later, playing a collective cover of People Have The Power, and then Bono's outfit left the stage so they could perform alone. They've now rescheduled the shows they'd been forced to postpone.

Hughes tells Rolling Stone: "Bono knows I'm a Christian and he knows I'm a mamma's boy. The day after the attack a courier came with a phone and a note that said, 'This is from Bono. Make sure you call your mom.'

"I thought that was awesome - it was the first time 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."

Bono later called him to offer advice and support. "I felt like the best person to ask is someone who's rubbed elbows with world leaders," says Hughes. "He just prayed with me on the phone. He kept my head off things. Then U2 visited the memorial site - that was important to me because I really wanted to be out there. I didn't want to be in some safe house.
