I've just found this thread!

Anyone interested in Kemp Owen should get a copy of Fay Hield's CD "Looking Glass" from 2010, as she has reworked the text further to include the belt, ring and sword from Child's A-version. Her text is given in full in the CD insert, so I won't reproduce it here, as we'd probably be breaching her copyright.

Fay has also modified the tune to produce occasional B-music (as in Nic Jones' "Little Musgrave"). Although the result may be some way from Mrs Brown's original tune, all I can say is, it works extremely well.
