Thank you very much for providing this sonorous and evocative sound. It reminds me of holidays in Maroochydore pre-development in the 1960s. I have used it as part of a collage in a piece called "A Cure for Serpents" which is listenable and downloadable on SoundCloud here: https://soundcloud.com/ivodne-galatea/a-cure-for-serpents
Holy-moly!! This dog is singing an old nursery-rhyme which goes something like:- This old man,he played four, He played knick-knack on my door, With a knick-knack,paddy-wack, Give a dog a bone, This old man came rolling home.
