I liked Ace and Taylor, too. (I'm still learning the names). The Wanted Dead or Alive guy has a stronger voice but he didn't deviate from the original recording. Ace and Taylor took their songs and made it their own.
I personally think Taylor (the gray haired guy) is phenominal.
I liked him from the first second of his audition when he had chosen "A Change Gon' Come" for his audition and really nailed it... accapella no less...
That dude has an incredible voice... I don't even think he needs the American Idol competition to have a sucessful career in music... how he got a full head of gray hair at the age of 29 is something I've never seen before.
He rocks!
