Over the last few weeks I've accidentally aquired or otherwise been introduced to a small shambolic miscellany of themed folk song CD's:
One a collection of 'Sailors Songs and Sea Shanties' from my father who couldn't get on with it,
another a collection of Celtic folk songs with magical themes called 'The Fairy Dance' (!) initially from bluddy Past Times of all places (including a great abridged version of Tam Lin that I've never seen anywhere),
another was Chumbawumbas' 'English Rebel Songs',
and most recently Anne Briggs 'Bird in the Bush' a collection of erotic folk songs.

I've found these CD's quite interesting as introductions to different types of traditional song, so I wondered what others here might recommend as good little introductory collections on CD, of equivalently themed folk songs?
