"London's Burning" is a traditional children's song with popular myth thinking it is about the Great Fire of London in 1666. However it predates the Great Fire and was originally called "Scotland's Burning"! The lyrics of each verse follow a pattern where each line is composed of a single short repeated phrase, just like Frere Jacques. This structure makes the song ideal for singing as a Round, and here is the music for the Round Version of London's Burning.
