the mention of a lawyer (un avocat) made me think of
My mother chose my husband;
A lawyer's son was he.
And on my wedding night,
He came to bed with me,
Ah, ah, ah! That's not the way to---
Ah, ah, ah! That cannot be!

And on my wedding night,
He came to bed with me,
He bit me on the shoulder
which nearly broke my knee
Ah, ah, ah! That's not the way to---
Ah, ah, ah! That cannot be!

etc (I see that the song is in the Digital Tradition on Mudcat).
I learned it from the singing of Pete Seeger, who said that "My Mother Chose My Husband" was a translation from the French. I see that Andrew Rowan Summers said it was a Breton song. I'd love to see the French lyrics (and are there also lyrics in Breton?).
