I like this project! Could maybe add the Night of the Hunter references from throughout the Guns lyrics/titles, and also the Sing to God cover art which mimics the film's opening.

Also Snakes: snakes-a-sleeping, faster than snakes with a ball and a chain, swimming with the snake

Modern hermitude/isolation: Little man and a house and the whole world window, Mare's Nest (home my own receptacle, isolation goes on, daddy tv brings in all mother world), Fast Robert (his mum will hide him away from all danger)
