Shaw, who recently won series three of the ITV series "Dancing on Ice," has previously appeared on the London stage in Summer Holiday, as the Narrator in Joseph and the Amazing Technicolor Dreamcoat at the New London Theatre and as Janet Weiss in The Rocky Horror Show. She first came to prominence as a winner of the TV talent show "Popstars," out of which she became a member of Hear'Say, a group created out of people who had appeared on the show. Though they sold more than three million records worldwide, they broke up 18 months after they were formed. Casey previously appeared as Velma in the West End production of Chicago in 2000, 2002 and 2004. She has also appeared in the West End in lead roles of productions of West Side Story and Sweet Charity; in 2005, she originated the role of Dot/Marie in the Menier Chocolate Factory's production of Sunday in the Park with George, but missed out on the subsequent West End transfer when she became pregnant. She was replaced by Jenna Russell, who is now also re-creating her performance in the current Broadway run of that show.

Also in the Chicago cast with them will be Terence Maynard as Billy Flynn, Victor McGuire as Amos Hart and Sue Kelvin as Mama Morton. To book tickets contact the box office at 0844 412 5652 or visit www.chicagothemusical.co.uk.
