Dankworth died on 6 February 2010, hours before a planned concert at the Stables theatre in Wavendon to celebrate the venue's 40th anniversary. He had been ill for several months following a concert tour in the United States. Despite her grief, Laine performed at the 40th anniversary concert, along with the John Dankworth Big Band and several members of her family – only announcing his death at the end. Laine's decision to perform featured on newspaper front pages all over the world, including a full photograph of her on the front page of "The Times".
