Numerous traditional songs mention London as their locale. Examples:

some versions of Butcher Boy: "In London city I did dwell ..."

some versions of Barbara Allen: "In London city where I was born, there was a fair maid dwellin'"

Blow the Candles Out "When I was apprenticed in London ... "

or

"I was a chambermaid down in Drury Lane" from Bell Bottom Trousers.

These examples might be multiplied many times.
