Nigel - I really meant Folk tunes rather than POP. That said, the Little White Duck was one I don't recall hearing, nice words for singing to the ducklings if I knew the tune.
I am not into Disco Duck, but there are some nice animated gifs of ducks on the web page. Some of the other songs on the same website are much better as songs.
Thanks for the thought!
Quack!
Geoff.
