It was of course absolutely right to experiment and innovate, it was a thrilling time for music. Whether experiments actually lead anywhere, though, you can't really tell at the time. Forty years on, I find it interesting(and often amusing) to see which of our efforts carried on and led to other things, and which didn't.
    If you drive down Porlock Hill(Exmoor) there are some little escape roads. If your brakes fail, and you are going a bit fast, you can turn off into one of these sideroads, and end up stuck fast, but safe, in a massive pile of sand. While the rest of the traffic carries on down the hill, somewhat more cautiously, reaches the bottom and thence to other destinations. The history of the English folk revival is somewhat similar. Of course, the question of which are the escape routes, and which is the main drag, might cause the odd argument!
