Julian Cope presents Head Heritage

But my point is that you wouldn't invest hundreds of hours in producing joints you'd never produced before. It doesn't prove the pre-Stonehenge landscape was covered with round timber structures comprising uprights and rings of lintols but it does suggest it was....

As for pushing their talents too far, each lintol has three or four joints of two different types and is curved in one plane and tapered in the other and fits into the ring pretty well so it's quite a good effort.
