Eurovision stars compete for anniversary special

Music stars including Abba and Celine Dion are to compete against each other to celebrate the 50th anniversary of the Eurovision Song Contest.

Viewers will pick fourteen acts from the show's past five decades - who have included Lula, Bucks Fizz and Julio Iglesias - and the chosen artists, or tribute bands, will perform against each other in Denmark.

Fans across Europe will then vote for the all-time best Eurovision stars during the competitive concert in October.
