Taylor Swift's string of celebrity guests on her Speak Now tour continues, as she travels the globe dazzling audiences with her own music and surprising them with covers from all genres, often accompanied by a fellow music superstar. Fans at last week's show in Austin, Texas were treated to a performance by one of their city's biggest success stories, Shawn Colvin. The pop/folk songstress joined the country superstar for a duet of the tune that won the Grammy for Song and Record of the Year when Taylor was just eight years old, 'Sunny Came Home.'
