By the way, no one seems to have said anything about the song's origins in this thread. Can anyone offer any more information than is in the French Wikipedia article about the song, which Google translates a bit stiltedly as follows?

The song, presented in eighteenth century peddling booklets, is inspired by a previous one, The Woman Drunk, which was transcribed in 1749 in Bressan dialect. Among his words are the couplet "Si je meurs, que l'on m'enterre dans la cave où est le vin, les pieds contre la muraille, la tête sous le robin". This verse is found in various variants: Catherine Has Her Hair or The Sickness of the Drunk Girl; The Old Mathurine, and in a play by Eugene Labiche. Previously, the theme of Knights of the Round Table as synonymous with wine friends was already present in the 17th century: in 1643, a song 7 by André de Rosiers de Beaulieu begins with these verses:

Children of Love and Wine, Knights of the Round Table ...

Le Roux , in his comic dictionary, mentions in 1718 that "we call knights of the Round Table those who like to be long at table."

(The most interesting part of which, I think, is that the reference to "Chevaliers de la table Ronde" has apparently got nothing to do with Arthurian legend, but is a French metaphor for someone who enjoys carousing.)
