Phun City was a rock festival held at Ecclesden Common near Worthing, England from July 24 to July 26, 1970.
Organised by Mick Farren, the festival was notable for having no fences and no admission fees. It was not intended to be a free concert, but funding was withdrawn a few days before the event. Rather than canceling it, the organisers told the scheduled bands who turned up that they would have to give their services for nothing. Remarkably, most of the acts stayed on. They include the MC5, Pretty Things, Kevin Ayers, Steve Took’s Shagrat, the Edgar Broughton Band, Mungo Jerry, Mighty Baby and The Pink Fairies.
