In a very special performance, Billy Ray and Miley sing a song called "Ready, Set, Don't Go." Billy Ray says he wrote it about the day their family found out Disney had picked up Hannah Montana. "We knew as a family that we needed to move to Hollywood," Billy Ray says.
As the rest of the family headed off to California, Billy Ray stayed back to tie up some loose ends. "As they drove off, it was that moment of realizing that I was letting go, you know, that my little girl was growing up and there was a lot of change around the corner. And I walked in the house and leaning against the wall there was my old guitar," he says. "For me, music has always been my greatest form of therapy and I just picked up that guitar and this song just came to me, and it's about letting go as a parent."
