"I just know that he's Robbie Williams - he's massive, that's all I know! He nailed it. Working in the studio with him was cool. I got there at about six in the afternoon and then stayed until six in the morning. We only worked for like two hours, the rest of the time we were just chilling out the back. The way Robbie handles everything... he's a star, but there were never any pretensions, no ego. He put effort in."
