The book that Mrs Duck mentioned is called 'Diguedondaine' by Ejnar Kampp published in Copenhagen (Wilhelm Hansen, Musik-Forlag) with 100 songs suitable for children (words, music, chords).

It might be hard to find, though, being a 1970s Danish book about French folksongs. I could maybe copy a page or two and send them by email.

Did you know that the Danish for bookseller is boghandel?
