There are several Morris versions of Greensleeves, although most will be found under the name of "Bacca Pipes", as the tune was often used for a solo dance round a pair of crossed clay pipes (English equivalent of the highland sword dance?).

Anyway there are Bacca Pipes from Ascott-under-Wychwood, Bampton, Headington, and Hinton, Greensleeves from Longborough and Stanton Harcourt traditions. I can post ABCs of any or all if required.

Wassail! V
