Video: Jacob Lusk Sings "Man in the Mirror" by Michael Jackson on April 6

Jacob Lusk isn't a rocker but he made this week's theme work for him. The contestant sang a poignant rendition of Michael Jackson's "Man in the Mirror" — a song close to his heart. The judges applauded Jacob's decision to stay true to himself. [Loved Jacob's performance? Watch his rendition of Elton John's "Sorry Seems to Be the Hardest Word" from last week.]
