I'm sure that this little known Fish Slapping Dance" ritual was inspired by the Morris Men of the UK......
Traditional English May Day rites and celebrations include Morris dancing, crowning a May Queen and celebrations involving a Maypole. Much of this tradition derive from the pagan Anglo-Saxon customs held during "Þrimilci-mōnaþ" (the Old English name for the month of May meaning Month of Three Milkings).
May Day has been a traditional day of festivities throughout the centuries. With Christianity came agricultural feasts such as Plough Sunday (the first Sunday in January), Rogationtide, Harvest Festival and May Day. It is most associated with towns and villages celebrating springtime fertility and revelry with village fetes and community gatherings. Since May 1st is the Feast of St Philip & St James, they became the patron saints of workers. Seeding has been completed by this date and it was convenient to give farm labourers a day off. Perhaps the most significant of the traditions is the Maypole, around which traditional dancers circle with ribbons.
The May Day Bank Holiday, on the first Monday in May, was traditionally the only one to affect the state school calendar, although new arrangements in some areas to even out the length of school terms mean that the Good Friday and Easter Monday Bank Holidays, which vary from year to year, may also fall during term time.
