As Ninian said, they were a part of the commune/free festival scene of the 1970s. After Daevid Allen quit Gong, he and Gilli Smyth hooked up with Here and Now and took Floating Anarchy on the road, frequently playing for free. This was documented on the Live Floating Anarchy 1977 LP, released for the proncely sum of two pounds fifty (about half the price of a regular album back then). The cover featured the instruction to pay no more than the recommended price, 'but better to rip it off if you can'. It's space rock in the Gong/Hawkwind/Ozrics style, with lots of bubbling synths and loose but tight jamming. I don't recall seeing it on CD, but the Charly Gong compilation Other Side Of The Sky has about half of side one and all of side two.
Allen subsequently quit and went to New York, where he made About Time with Material under the New York Gong monicker. Here and Now remained a fixture on the festival circuit, sometimes releasing cheap albums. In addition to those already mentioned, there was one called There and Then. I haven't heard anything about them for years, but it would be nice to think of them turning up and playing for free at some of today's market led, consumer focussed festivals.
