the Unthanks (what an apt name)
Well, Carol, (what an appropriate name), it is the name they were born with so I reckon they should use it. Their dad George Unthank was (is?) a member of that very fine folk band, The Keelers and the sisters have grown up in the music. Don't like them as singers myself, but seeing the pair of them running a festival clog/step dance workshop to around 100 mainly teenage, mainly female participants made me realise what an important job they do. The enthusiasm and skill with which they conducted their workshop won my admiration.
