I remember singing this as a UK Girl Guide, back in the 60s. I was sure I had a copy in print from then, but have just sorted through all of my songbooks and it's not there - not even in the Chansons de Notre Chalet.   I also remember the story of the dying child - I always thought of this child as being in the Netherlands, but that might just be because of canals and barges.

Wish I could come up with an origin!
