Elvis Costello：Meaning of Revolution #49 Songmeaning

I'm sorry, but there seems to be a confusion in your query. The lyrics you provided are not from Elvis Costello's song "Revolution #49." Furthermore, the lyrics you shared do not seem to match any known song by Costello. Consequently, I am unable to provide an explanation or story for a song that does not exist. If you have any other questions or if there is another song you would like to discuss, please let me know.
