I liked this idea of (Jack) almost lumbering onstage; that he’s not this butterfly flying through the guitar. I wanted him to be very sort of muscular. And Neil, I love the way he plays the guitar. When Jack is onstage is when he’s most himself. He takes his hat off when he goes on stage. He sheds it all. That fuels it and he’s been living on that for years — that and painkillers. But that’s where he gets that fix. And Neil, when I watch him play, it’s like he’s in a trance.
