New Age circa 1970-80? some will probably have joined the so-called gipsy/tinkers community scrounging off the state calling themselves 'green', the conservators of nature, Don't forget they will be about 50 years old or more by now, some living in a squat dreaming of the all hash and free love they wished they could have got, and what we thought they were all getting.
I think they are still around but after all that free love some of them must have generated quite a community by now. I heard of one group who bought a house and land as a commune somewhere in the south.
