Joshua Ledet 'stellar' on Sam Cooke to close 'American Idol'

With Joshua Ledet doing Sam Cooke's "A Change is Gonna Come" to close "American Idol," we could get a special moment.

He starts with emotion right away; this is a deeply meaningful song, and he gets that. He's keeping the voice in check, starting to let it loose as the song goes on. Just floats nicely on the chorus; winding it up strong.

No moment for me, but well-done -- judges stand and give him an ovation.

"Your voice just climbs inside of everybody and changes them for that moment," says Steven Tyler.
