Multi-award winning Scottish solo artist, Kt Tunstall has written a theme song especially for Ruby Blue. She is currently riding on a crest of a wave of success having recently broken the notoriously hard American music market with a Grammy Award Nomination for this year's ceremony in the spring.

In addition to the Mercury Music Prize nomination, Tunstall received three Brit award nominations when they were announced on 11 January 2006. Tunstall was nominated for Best British Live Act, British Breakthrough Act, and British Female Solo Artist. At the ceremony on 15 February 2006, Tunstall performed "Suddenly I See" and won the award for Best British Female Solo Artist, remarking that she wished to share it with fellow nominee Kate Bush.
