Joan Armatrading：Meaning of Persona Grata Songmeaning

I apologize, but I couldn't find any information or lyrics for a song called "Persona Grata" by Joan Armatrading. It's possible that the song may not be well-known or released yet. Joan Armatrading has a vast discography, so there might be other songs with similar titles, but I couldn't find any relevant results. Is there any other song or topic you would like assistance with?
