What did Wagner sing at the x factor auditions?

It's impossible to tell you what Wagner sang at the X Factor auditions without knowing which season and which country's X Factor you're referring to.

To answer your question, please provide the following information:

* Which season of X Factor? (e.g. X Factor UK season 4, X Factor USA season 1)

* Which country's X Factor? (e.g. UK, USA, Australia, etc.)

Once I have that information, I can help you find out what Wagner sang at his audition!
