L’EMPEROR, SA FEMME ET LE PETIT PRINCE is a French folk song of the second half of the 19th century, making a reference to Napoleon III, Empress Eugénie and the Prince impérial. [All three are buried in Saint Michael's Abbey, a Benedictine abbey in Farnborough, Hampshire.] This song is used to teach the days of the week to children in French. Wikipedia

Lundi matin, L’empereur, sa femme et le p’tit prince
Sont venus chez moi, pour me serrer la pince.
Comme j’étais parti, Le p’tit prince a dit :
« Puisque c’est ainsi, nous reviendrons mardi. »
