Soul Sister: The Tina Turner musical

The dramatic story of the lives and careers of Ike and Tina Turner is being told in a new musical.

Soul Sister follows the pair from their first meeting to their transformation into music royalty, and the dark shadow of drugs and domestic abuse which eventually destroyed their relationship.
