If you didn't know already, Ed is a huge fan of the show, Which I am sure you are too. It's been said that Ed will actually have a roll on the show and he spilled the beans on what he will be doing.
Ed will be a singer, surprised? no? me neither. In a recent interview he added who will be in the scene and who say's what. It kind of seems that in the interview he doesn't care but Ed is probably more excited than you fans out there.
