I believe this one is actually Croydon. I'm led to believe that counts:
Some very obvious Clash songs. Too obvious to mention except I just wanted to say I never liked the track London Calling (Unpopular Opinions thread>>>>>). Guns of Brixton however, is excellent.
And beyond the London Calling album, the Clash had White Man in Hammersmith Palais, Capital Radio, Guns on The Roof (pretty sure the pigeon shooting was on a London roof!), London's Burning, Stay Free (London references). Probably lots of others.'bankrobber' isn't specifically london, but the video is c. 1980 lewisham
big audio dynamite also have a few london songs - 'tighten up vol 88' (brixton), 'the battle of all saints road' and 'harrow road'
