K.J. Yossman Catherine, the Princess of Wales, made a surprise appearance during the opening of the Eurovision Song Contest’s grand final on Saturday evening alongside Andrew Lloyd-Webber, rapper Ms Banks and last year’s Eurovision winners Kalush Orchestra, who hail from Ukraine. The princess, who is married to Britain’s Prince William, appeared in a pre-recorded clip playing an instrumental version of Kalush Orchestra’s winning song “Stefania” on the piano, which she recorded in the Crimson Drawing Room of Windsor Castle earlier this month. The clip was part of a montage of different artists – including Lloyd-Webber and Ms Banks – who performed a version of the song alongside Kalush Orchestra themselves. Also featuring in the line-up were last year’s runner-up Sam Ryder, Ballet Black, Bolt Strings, and Joss Stone.
