Steele, who was the mastermind of the event, was very surprised that the teen pop star suddenly came to the stage and asked if she could sing at the event. With the approval from the country star, the teen singer then performed a song titled "Simple Song", which was recorded by her and written by the 46-year-old singer. Not only that the song also happened to be the country singer's only song that was on her son's iPod the day he died.

After performing "Simple Song", Miley then asked Steele to do a duet with her singing his hit single "Hollywood Girl". The country singer then commented about the pop star's request stating, "Miley might live in Hollywood, but in her heart, she'll always be our Tennessee girl."

The event's itself was actually a fund raising concert held by Steele to remember the death of his 13-year-old son Alex la Vasseur in 2007. On the show, that was staged at the Jim Warren Park in Franklin, Tennessee, beside Miley, the country singer is also being accompanied by other famous names, such as Michael McDonald and Miley's dad Billy Ray Cyrus.
