She mentions the song in an interview with The Guardian, but it is not on that album, First Farewell

The Young Virgin

"Your new album, First Farewell, is moving and playful. One song, Lubrication, has a lyric about older bodies needing “grease to help ’em do their jobs”. You’re relishing the euphemisms as you sing, aren’t you?

"'I am! Folk is full of raunchy songs but they’re not often sung. I have another song called The Young Virgin, where a woman has 40 lovers who bring along the tools of their trade: a blacksmith’s anvil, the glistening pipe of a druggist, the lance of a doctor,,,'"

The song is not on this list and the song title is not showing in an internet search.

Did you hear her singing it live or was it on an album?
