Someone posted a link to an article, in the comment section for this video, that explained why the song existed, but I decided I wanted to tell my side of the story and talk a little bit about the history behind "Sonny."
The title of the whole piece is "Gloriously Baffling: The Real Story Behind 'Sonny the Monster'" and will roll out as follows:
Part 1 (2/25): An introduction and some history behind Anacrusis
Part 2 (3/4): The Anacrusis originals and the real reason I picked "Sonny" to cover
Part 3 (3/11): Recording "Sonny" and the song's legacy
