It is Flora Day in Helston when men and women and boys and girls take to the streets in a series of dances to bring on the summer.
It seems the whole town comes out to celebrate - whether dancing, playing or just watching from the sidelines.
The Liberal Democrats may have been facing a wipe-out across the West Country but it didn't stop former St Ives MP Andrew George taking part in one of Cornwall's most popular customs.
Andrew George has had a role in the celebrations for many years and today - even though he was still waiting for the result in his constituency - stepped up for the Midday Dance.
Later, Mr George was to find that he had indeed lost his seat - to the Conservative Derek Thomas by 2,469 votes. It was the last result declared in the General Election and completed the transformation of Cornwall from a Lib Dem stronghold since 2005.
The people of Helston have been celebrating the most important event of their year - Flora Day. Despite the rain, thousands crammed into the streets to see dancers weave their way through the town.
The ancient festival is one of our oldest surviving customs and marks the coming of spring. Kathy Wardle was there.
