The Beatles' Yellow Submarine Turns 30 "Edelmann is given credit for inventing the Blue Meanies to serve that role. In an interview, Edelman added yet another to those who contributed to the film's script. He said, "There was never one script. We had about 20. Roger McGough was responsible for much of it." McGough was a Liverpool poet who was brought in to add a Liverpool flavour to the soundtrack. He was paid £500 for his work, but was not given screen credit." (Accessed 19 October 2014.)
