The mention of Tam Lin above, prompts me to say, if you ever get the chance to see Dick miles - go, and get him to sing it - fabulous.
My favourite spine-chilling song at the moment is Florence Wyndham, sung by Tim Laycock but learned, I think, in a folk club in the seventies.
Woman dies, gets buried, husband grieves.... Sexton goes at night to dig up woman and rob her of her valuables...BUT When sexton tries to cut off woman's wedding ring - woman wakes! Sexton dies - woman returns to husband - who also gets rather a shock!!
