On 15 July 2006, as part of BBC One's "Sport Relief" charity spectacular, Klass appeared as a special guest in the "Question of Sport Relief" segment. Klass's appearance involved her playing a variety of TV sport theme tunes on a grand piano. This part of the fundraiser was based on the BBC's popular "A Question of Sport" quiz show and was hosted by Sue Barker. Guest panellists on the show included Nancy Dell'Olio and Zara Phillips, who played alongside the regular team captains Ally McCoist and Matt Dawson.
