He was only six years old but he remembers the moment vividly.

Dan Snow was with the rest of his family being led by their television presenter father Peter around the scene of one of the bloodiest battles in history.

The village a few miles south of Brussels was known as Waterloo.

And trudging round the land where Wellington and Napoleon faced off for the first and last time, Dan turned to his father and said when the 200th anniversary came around, he would mark it with his father.

Twenty years later, and true to form the Snows have marked the occasion in their own way - by writing a book and performing a stage tour around the country.

Sadly, when it arrived in Worthing, Peter was missing due to a leg infection.

But Dan held his own, talking for more than an hour on the battle, giving a virtual tour, introducing the characters, and analysing the key moments - all with great energy, enthusiasm and humour.

It was just a shame that dad Jon was missing - as with him the pair could have bounced off each other, as they have done so well on TV programmes in the past.

The evening ended with a simple question: will the Snow family continue their historical legacy?

"Certainly so," replied Dan. "We have the best heritage in the world and kids are fascinated by it. The question we must ask is why do adults lose their interest in history?"

Such talks like this will be a great re-introduction for those who may have lost their way.
