These were sung by the City Waites on one of their early LPs (1970s, not reissued on CD):

(this is quoted from this useful looking site with minor spelling corrections)

"When Celia was learning on the spinet to play
Her tutor stood by her to show her, to show her,
To show her, to show her the way.

She shook not the note, which angered him much
and made him, and made him cry "Zounds! Tis a long prick,
a long prick, a long prick'd note you touch.'

Surprised was the lady to hear him complain
And said, and said and said "I will shake it. I will shake it when I come to it again."

The song is sung by at least three people. When all three verses are
going in round fashion, you get

"To show her, a long prick, I will shake it."
when I come to it again."
