This is a variant of a variant of a web classic – I'm not even sure the original was the Llama Song, but that's the one I'm aware of. Anyway, this is me simply polishing up an excellent and hilarious version of the Llama Song called The Dalek Song, by The Partyman (based on the Llama Song by Burton Earny, and The Sawyer Song by Jy Yang and Cordelia Yip).
