Okay, okay, by popular demand! I see by the logs of what people search for when they come to this website that some of them are looking for The Llama Song, otherwise known as “Llama Llama Duck.”
I first heard about it from a friend whose young children (and wife too, I think) were addicted to it.
I don’t guarantee the child-friendliness of any of these things, though!
This is the site that claims to be the original: http://burtonearny.deviantart.com/art/The-Llama-Song-9311361
And here is a YouTube link to a page listing all sorts of llama songs.
