When we moved to East Sussex we'd never heard of the bonfire groups. Many towns and villages hold evening marches in full regalia carrying flaming torches and accompanied by various types of marching bands.
Some villages dress up as pirates, others WW1 or Boer War soldiers, others period costume, others cowboys, etc., etc.
Half way round the procession stops off at a pub, using beer mugs they carry swinging from a belt.
At the end, there is a village or town bonfire, accompanied by fireworks. It's all very colourful, brash and noisy, and it's all in aid of charity.
Lewes is probably the most well known where last year they burned an effigy of Trump.
