According to Lydon, "Banging the Door" "came about as a rant against the fans who found out my address in London and used to come around every night, banging away on the door and shouting 'Johnny! Johnny!' through the letter box. Nearly drove me mad!" In a 1980 interview with "The Face", he comments: "It's much, much worse than it was in the days of the Sex Pistols. I've even had them pitching their tents on my front doorstep [...] I just don't let any of them in anymore. I just don't answer the door." Keith Levene: "Martin played the drums and I played the bass. Then I added synth to that." Nick Launay: "Keith was very into these synthesizer boxes that plugged into each other with little red cables, I think it was made by Roland. It was a bit like the giant Moog synth that Kraftwerk used, only in miniature. You can hear it on 'Banging the Door', it sounds like an evil giant frog!"
