Ron Prince got a phone call earlier this year from a friend telling him to turn on the TV. Like, right now. "He said, 'Ron! Ron! That's your girl on TV! On 'American Idol'!" When Prince clicked on Fox, he saw Crystal Bowersox, the young woman who used to come by his Englewood home studio, sit on the floor and play her guitar. Prince had been intrigued enough by what he heard that he'd recorded some of her songs.
