Back in 2010, when Tokio Hotel was in Taiwan, they appeared on television for an interview. As part of their interview, they had the opportunity to critique a couple of young fans performing Tokio Hotel songs. Perhaps this will give some insight into how Tom and Bill will do as judges?
Bill was kind, Tom looked sleepy.
Somehow how I think 2013 (did I just say 2013, omg) will bring us fiercer judges. Of course, the people will probably not be doing Tokio Hotel songs.
