Plaisir d'amour, Lyrics Jean-Pierre Claris de Florian (1755-1794); Music Johann Paul Aegidius Martini (Martini il Tedesco), ca. 1775.

Not attributed in the DT. Not traditional, but certainly 'traditional' as far as its popularity is concerned. This is one French song that everybody has attempted.

Errors in French in the DT-
Chorus, sung at the beginning, end and between each verse- Plaisir d'amour ne dure qu'un moment (not qu'on)
1st verse, line 1, quitté line 2- Elle me quitte et prend un autre amant (quitte, not quit, unaccented; amant, not amour)
2nd verse, 2nd line- Vers ce ruisseau qui borde la prairie (Vers ce, not Vera a; borde, not bord).
3rd verse, 1st line, me répétait; 2nd line- L'eau coule encore, elle a change pourtant. (not Mais l'eau coute; changé).

The song was recorded by Joan Baez, but her words were not exactly as shown in the DT. She substituted 'instant' for 'moment' in the chorus (not an error in French, both are acceptable I think.
Nana Mouskouri sang the original as written by Claris de Florian.
