Winchester's Hat Fair, a ramshackle and chaotic and quite charming May street arts festival, is inviting proposals from artists and companies interested in performing there.
In the best traditions of the festival, there's not a lot of information. Traditionally Hat Fair has been a busking festival (the hat is the hat that you put down at the end of your performance to collect money), but the site announcement seems pretty clear that only invited artists are allowed to perform at the festival, and makes reference to commissioning activities.
See here for all there is to know, and send promotoional materials to 5a Jewry Street, Winchester, Hampshire, SO23 8RZ, United Kingdom by 31 January 2011.
