The Clevedon event is believed to be the only one where dancers celebrate on land and in the water at the same time.
Last year, the event raised just over £1,000 for SARSAS.
“They were delighted that we danced for them,” said Pairaudeau.
Celebrations of the song and mass recreations of the famous dance, which was originally filmed on Salisbury Plain in Wiltshire, have been taking place since 2013.
They have since spread around the UK and the world.
“Who wouldn’t be delighted by it?” said Pairaudeau.
“It’s a testament to the power of the song and how much it means to people, and the book.
“What a wonderful artist Kate Bush is, it’s such an iconic dance, the video is iconic and I really hope she gets some pleasure out of us prancing about,” she added.
