This aye night

Actually it's not "This Ay Nicht", which I really like because it's all doomy winter and has that line in it about fire and sleet and candlelight. (The real line is "and fleet", ie floor-space, which makes more sense - but we like "sleet" and so do the Baebes.) But this song is "Tam Lin", which is equally faerie-dusted and comes from the Mediæval Bæbes' album Mirabilis. So that's why.
