I was checking out the youtube videos of Adam Lambert's portrayal of the song "Mad World" at this year's American Idol 2010 on the way home just now and I think his version was actually very hauntingly fantastic with all the stage lights, little stage movement from him, and yes, he deserved the standing ovation by Simon Cowell. I couldn't attach the youtube, so I am providing the link below:
There was also a version performed by the Australian Idol 2007 contestant Ben McKenzie, which was also slightly different. The critic's comments were kind of interesting but positive. Are they all so nice on the Australian Idol?
But I still prefer Adam's take on the song.
