There are some versions from here to there, including one in Lemosin Occitan.

Here is an Occitan version of it as sung by Maria Roanet (Marie Rouanet in Fr.) in the early 70's -it's the one I knew and never considered it a children's song.

La bèla Marion se'n va al molin Amb sa tuqueta plena de vin A chaval sus son ase La don don don A chaval sus son ase La bèla Marion. Quand lo molinièr la vegèt venir "Bèla Marion, veni aicí Passaràs la primièira La don don don Passaràs la primièira La bèla Marion. Lo molinièr se metèt a la careçar O molinièr laissa me'n anar Lo lop m'escana l'ase La don don don Lo lop m'escana l'ase La bèla Marion. O bèla Marion, laissa-lo l'escanar Ai cent escuts per te donar Ne compraràs un autre La don don don Ne compraràs un autre La bèla Marion. Quand son paire la vegèt venir Ma filha qué menas aquí? Aquò n'es pas nòstre ase La don don don Aquò n'es pas nòstre ase La bèla Marion. O mon paire que sètz vos camèl Totes los ases càmbian de pèl Aital a fach lo nòstre La don don don Aital a fach lo nòstre La bèla Marion.

The beautiful Marion goes to the mill With her gourd full of wine A-riding her donkey La don don don A-riding her donkey The beautiful Marion. When the miller saw her coming "Beautiful Marion, come here You'll go first La don don don You'll go first." The beautiful Marion. The miller started to caress her "Oh, miller, let me go The wolf is strangling my donkey La don don don The wolf is strangling my donkey." The beautiful Marion. "Oh, beautiful Marion, let it strangle him I have a hundred crowns to give you You'll buy another one La don don don You'll buy another one." The beautiful Marion. When her father saw her coming "Daughter, what do you bring here? This is not our donkey La don don don This is not our donkey." The beautiful Marion. "Oh father, what a fool you are All donkeys change their skin Thus did ours La don don don Thus did ours." The beautiful Marion.

Here is a more recent rendition with a different tune.

Quand la Marion se'n va al molin Pren sa conolha fiala de lin A caval sus son ase La pinga pinga pon A caval sus son ase La bèla Marion. Lo molinièr la vei venir De rire se pòt pas tenir "Estaca aquí ton ase! La pinga pinga pon "Estaca aquí ton ase!" La bèla Marion. Del temps que lo molin moliá Lo molinièr la caressiá Lo lop li manjèt l'ase La pinga pinga pon Lo lop li manjèt l'ase La bèla Marion. "N'ai cinc escuts dins mon borset Pren te ne dos daissa ne tres Cromparàs un autre ase. La pinga pinga pon Cromparàs un autre ase." La bèla Marion. Quand son paire la vei venir De plorar se pòt pas tenir "Aquò's pas lo nòstre ase. La pinga pinga pon Aquò's pas lo nòstre ase. La bèla Marion. Lo nòstre aviá los pès blancs Dos de darrièr dos de davant E las aurelhas negras La pinga pinga pon E las aurelhas negras. La bèla Marion. - O mon paire que sètz camèl Totas las bèstias càmbian de pèl Aital a fach nòstre ase." La pinga pinga pon Aital a fach nòstre ase." La bèla Marion.

When Marion goes to the mill She takes her distaff, she spins flax A-riding her donkey La pinga pinga pon A-riding her donkey The beautiful Marion. The miller sees her coming He can't refrain from laughing "Tie your donkey here La pinga pinga pon Tie your donkey here!" The beautiful Marion. While the mill was grinding The miller was caressing her The wolf ate her donkey La pinga pinga pon The wolf ate her donkey The beautiful Marion.
