Did the prog cover hill figures? Willmington, Cerne Abbas etc?
I'd be interested to know a bit more about the figures of Gog and Magog that were supposedly carved into the hill just beloe the Citadel in Plymouth ("Lost Gods of Albion" P Newman Sutton 1997).
Bristol has the legend of Goram the Giant.
Salisbury has a giant called Christopher - he's in the museum and gets brought out for May processions along with hob nob the obby 'oss (or used to when I was young - don't get back there much these days).
