The dude can sing, no doubt...but there is no feel to his voice. There is nothing unique about him, he sounds like a million other singers out there.

At the work do he sang at the other week, I was in the urinal before he started singing and was speaking to my wife on the phone and said something along the lines of "that Stan wanker from Idol is singing here tonight". I got off the phone, started washing my hands and then guess who comes out of the cubicle? Stan Walker. I felt like a dick.
