I think this is the girl who sang it - Kenzie Palmer. She also sang Temporary Home. Interestingly enough, Luke Laird actually commented on her performance.
And this is her from Idol tonight.
WOW!!! I love her already. The vocals is really beautiful!!! And she looks gorgeous and charismatic. I think, I will vote for this girl. I love the CHEMISTRY OF THE JUDGES, TOO. VERY ENTERTAINING.
