It's one of the most famous views in the world - and one of the UK's busiest ports. This is a rare chance to meet the people who work behind the scenes along the waterfront, and see over a million people turn out to watch a choreographed 'River Dance' by the ships in a memorable display that rekindles Liverpool's pride in its shipping heritage. The Mersey is also the backdrop for an annual charity swim - the rainy weather, tides, cold water and even jellyfish conspire against the brave souls raising cash for their favourite causes.
