From today you can get your hands on the official Comic Relief single, Walk This Way by Sugababes vs Girls Aloud.
With production by Dallas Austin, the ultimate girl supergroup puts a catchy new spin on the 1986 original by Aerosmith/Run DMC. 2005's official song was by McFly with an additional record provided by Tony Christie's Amarillo, championed by Peter Kay.
The single is available on CD or as a download and all profits go to Comic Relief.
