Speaking on the Mirror's Invite Only podcast, he said: "When I walked into rehearsals, the first thing Amy said to me was: 'You need to forget everything you have learned.' "My wife is a professional dancer in a commercial style, and when I went back home and showed her the video she said: 'What even is that? I don't understand.'

"At the launch show, what I was trying to do was literally to walk in a straight line, a simple two step forward. But I have never been more nervous than I was at that moment, because I'm used to making everything big. "Instead I had to do something that is alien to me, but also control it, and make it elegant and classy.
