As has been pointed out, the "Pikey Caravan" incident took place in Firle and it happened early in the Bonfire Season - each village has their own weekend date. As a result of this incident the Firle Bonfire Society was banned from taking part in the main Lewes celebrations.
Word went around that the rougher element from Firle would be out to disrupt the Lewes celebrations that year but I don't think anything came of it.
I can remember a few shouts of "Nobody likes us, we don't care - we're Firle!" but compared with the same chant from a Millwall football crowd it sounded pathetic.
