Let's talk about Taylor Swift; how was it performing with her back in February?
"She's amazing. Her team called me about three weeks previous to the show and said that she really liked the song. I thought it was the whole team's plan, but when I turned up she genuinely loved the song and we rehearsed together, and she was amazing."
Did she pick up the lyrics straight away?
"Yeah, she'd learned it; her whole band and her had learned it. She was just - she was amazing. She was really fun, really tall."
Did you talk about writing together in the future?
"I don't know. I didn't even think about that - I was more concerned with the fact that I was going up on one of those pop things on stage. I was more thinking, 'S**t, I'm gonna fall over'. No, I haven't spoken to her about that."
