"Ian Sinclair pretty much invented the practice of psychogeography"

I think he was followi8ng in the footsteps of the neo-romantics, Peter Ackroyd, John Michell and, although it wasn't, of course, called that, the works of John Cowper Powys.

"John Clare probably has the best claim to be England's folk poet"

I wouldn't dispute that but also in the running are William Blake and, less well-know, Robert Bloomfield.
