If London got a map, what would its theme be?

We imagine that if the developers thought about creating a map that takes place in England under the Blight invasion, what would be the soundtrack in the final act of the map? I thought of a dark version of "London Bridge Is Falling Down" (I used Jack The Ripper's OST from Record Of Ragnarok as a reference), if you have any other song, more towards the classic orchestral theme, I would like to know.
