The singer said that he took matters into his own hands because he did not like the sound of Marcus Mumford and the gang warming up their vocals.
“We were playing a festival in Dublin the other week,” he told Australian magazine Brag. “There was this other group warming up in the next sort of chalet, and they were terrible.”
He added: “I said, ‘Shut them cunts up,’ and they were still warming up, so I threw a bottle at them. The band said, ‘That’s the Sons Of Mumford [sic] or something, they’re Number Five in charts!’. I just thought they were a load of retarded Irish folk singers.”
