Green's "Read All About It
" collaborator Emeli Sandé came to him with the chorus, which he loved. He told Irish State Broadcaster RTÉ: "It would've been easy to just do what most rappers do and chat a whole load of bravado that didn't really mean anything to anyone. But I really dug my heels in and got into the concept. That was hard because I had to make sense of Arthur and his sword and Avalon - which is the place he retreated to when he was injured - and the whole Lady of the Lake thing. I had to make that make sense to everyone else, so that took me a while to write. But I think spending the time on it really made it into the song it is. "
