Crystal Bowersox Performs 'People Get Ready' on 'American Idol'

Bowersox's emotion-packed cover of Curtis Mayfield and the Impressions' 1965 hit "People Get Ready" was like a greatest hits of past "Idol" moments.

There was the a cappella open, a nice homage to season four's Bo Bice, who famously performed "In a Dream" without instrumentation. We had a performance felt so deeply, it brought the singer to tears (think Fantasia's "Summertime"). And we had a family member in the audience that was a big reason for the heightened emotions, in this case Crystal's dad. She told Ryan Seacrest that just seeing him at the show for the first time brought her to tears.
