"The thing is, with Liam you just get into trouble all the time. When you’re 27 that’s brilliant. But there comes a point when you can’t be arsed anymore. I had a fight - a fight! - with him about the best Christmas song. We were in a pub and someone goes “Best Christmas single of all time?” Merry Xmas Everybody, Slade.” He goes “What do you fucking mean? What about John Lennon, War Is Over?” Who sings that at parties? That escalated into a fist-fight in the car park. My kids were like “Why’s Daddy got a black eye?” “He was fighting with Uncle Liam.” “What about?” “Christmas songs.” I won’t be that guy anymore."
