There is a new essay our on ann.skea.com: Michael Baldwin's "Ted Hughes and Shamanism". It was one of the essays originally slated for the collection of memoirs edited by Lucas Myers and Bertram Wyatt Brown in 2008/2009. The publishers (Louisiana State University Press) were eventually obliged to cancel  publication due to difficulties in obtaining copyright permissions.

Michael Baldwin is a widely published poet, novelist, essayist and short-story writer. He was a long-time friend of Ted Hughes and in this memoir he recalls their shared (usually sceptical) fascination with magic. He also writes of A. Alvarez's disparagement of Ted as a shaman.
