Davy Jones... Killian Jones. Pirate... Pirate. Coincidence. I think not. Father/son? I really hope Davy Jones is Hooks father. In the POTC films Davy removed he own heart and put it in a treasure chest- very Once Upon a Time-ish, would fit in nicely with theme.. & whirlwind of daddy issues.
Just a few years before his death, Davy Jones was still recording music (including a project with cartoonist Sandra Boynton). In this shot, he's recording the theme to a campy movie about a female superhero named "Sexina!"
