William: On Friday 29 April London is going to see one of the biggest events in its recent history: the marriage of Prince William to Kate Middleton. You're going to see some incredible pictures on your TV sets as anything up to 1.5 million people crowd round the streets to watch the procession from Buckingham Palace to Westminster Abbey and then back again. My name is William Kremer and this is On the Town. Come with me as I cycle the route of the royal wedding procession!
