I think it is the one by Roger Vermeer, heres a YT link from a Verchueren disc with the Valse de la fôret, a mere arrangement of a German or Austrian folk tune, that can be found in many folk tune collections for accordion
The second tune in the sheet music Au plaisir des bois is also a Germano Austrian folk tune, arranged and renamed with a French title. Happens all the time with popular traditional tunes.
Often these French musette accordion players or the arrangers simply renamed a tune.
Confusing if you want to look for the sheet music
eg the Elvis Presley song Love me tender, I found in an Irish song tune book at home, called Aura Lee:

A few years ago, someone asked me to find the sheet music of the tune Coucou by the accordionist Maurice Larcange.
Finally it turned out to be composed by Emanuel Jonasson in 1918

Many times the singers and players are getting all the attention, the Original composers and arrangers have long been forgotten. But not by the internet.
