Padstow in Cornwall holds its traditional 'Obby 'Oss (local dialect for 'Hobby Horse') festival annually on May 1st. Although the origins of the celebration is unknown, it is thought to be pre-Christian and to relate to the Celtic Beltane rites. Every year the locals begin the festival at midnight on April 30th, parading through the streets singing and decorating houses and local landmarks with greenery, flowers and flags. There are two 'osses', known as the "Old" and "Blue ribbon." During the day two dancers wearing crude horse costumes, representing either Old or Blue ribbon, progress through the town, each leading a merry throng of revellers. There are different traditional songs for both the night and daytime celebrations.
