Diamond Jubilee Pageant Master Adrian Evans has said excitement for the event is "rising" as the celebration approaches. Mr Evans said:
Excitement is rising as 20,000 individual participants prepare to take to the river on 1,000 vessels.
It's a massive production with some demanding challenges, but it's going to be an utterly spectacular Jubilee celebration.
I am especially pleased to be able to confirm the wealth of musicians, singers, choristers, composers and conductors who will be taking to the Thames aboard the ten music barges to entertain the viewing and listening public.
The Duke and Duchess of Cambridge are to join the Queen on her royal barge during the River Thames pageant celebrating the Diamond Jubilee.
The banner that will adorn the royal barge has been unveiled along with other details of the Queen's Diamond Jubilee celebrations.
