Waterloo Sunset and, if you want to be really tenuous, Victoria (I know it's about a woman!), both by The Kinks.
I Don't Want To Go To Chelsea by Elvis Costello.
There are several that mention areas of London in the lyrics but not in the title, e.g.:
Driving In My Car by Madness (mentions Primrose Hill and Muswell Hill)
Kayleigh by Marillion (mentions Belsize Park).
The Wombling Song by The Wombles (mentions Wimbledon Common, of course!)
Dedicated Follower Of Fashion by The Kinks (again) mentions Regents Street and Leicester Square, and sort of mentions Carnaby Street ("everywhere the Carnabetian army marches on")
