Cuckoo's Nest

"The Cuckoo's Nest", also known as "The Cuckold's Nest" is a bawdy Scottish song from the repertoire of Jeannie Robertson of Aberdeen. Her recordings of this song can be found on her EP I Ken Where I'm Going (1959), on the anthology Songs of Seduction (The Folk Songs of Britain Volume 2 (1961/1968), The Cuckoo's Nest and Other Scottish Folk Songs and Songs of the Travelling People (1953). Norman Buchan commented in the EP's sleeve notes:

A flourishing weed in fairly recent Scottish cultural developments was that phenomenon known as “The Kailyard (cabbage-patch) School”, which took its name from the “kailyard” reference in a song called The Bonny Brier Bush. The writers in this school sedulously fostered the curious conception of the average Scotsman as a pawky peasant, stupid, sentimental and altogether sickeningly coy. Here in The Cuckoo's Nest is a song calculated to smash any surviving remnants of kailyardery. This is a piece of healthy bawdry, set in a real and not a phoney kailyard. The cuckoo's nest itself is, of course, a conventional sex symbol, of a kind perhaps, more often found in English folksong.

The title, the "cuckoo's nest" commonly referred to female pubic hair and accompanying anatomy. It dates to at least the early 18th century.
Martin Carthy and Dave Swarbrick played the tune on their album Rags, Reels and Airs (1967) and The Acoustic Folk Box (2002).
