The "Wearing of the Green," printed by Such and in the Bodleian
Library (2806 b.10(218), is not the "Paddy, dear" song which I think is post-Civil War, nor the other version in the DT.
It has been posted by Gargoyle (24 June 99) in thread 11774, but never added to the DT, although it is, I think, the only pre-Civil War song of that name.
See: Wearing of the Green and other comments on that thread.
