The duo reveal the songs that shaped their respective musical journeys. James picks Tina Turner's epic Proud Mary rendition as one of his all-time greats and Beverley introduces him to Big Mama Thornton - a woman who taught Elvis a thing a two before revealing how she felt when the opportunity to sing with her idol presented itself. Plus, the raw stadium rock vocal of Steve Tyler, the soaring acoustic purity of Eva Cassidy, the intensity of Otis Redding and the passion of Prince. Whitney Houston sings live to an audience of millions, Tom Jones returns to Wales to deliver one of his classic hits and a pitch-perfect George Michael serves to blow the roof off Wembley stadium.
