There is a good example in the Oldham Tinkers latest rendition of "Peterloo". The original poem by Harvey Kershaw finishes with "The Free Trade Hall it stands today on the fields of Peterloo". The Free Trade Hall was sold off to private developers by the idiots at Manchester council and all but the facade was demolished to make way for an hotel. John Haworth, who wrote the music and jokingly calls Harvey a "derelict" post, now sings "The Free Trade Hall shoud stand today on the fields of Peterloo".

Folk process in action!
