I always liked the song Mother of pearl from roxy music. I wondered all the time who is the mother of pearl. I searched for a translated song text, there was used something like "the chosen one" as translation. I am no native english speaker, so I am not sure if this is a common meaning for "mother of pearl" in english. I found the wikipedia page for mother of pearl but i dont think this is meant in this song.
So can somebody explain to me the meaning of mother of pearl in this song? Is this just a common english phrase for a beloved person or has this some other meaning?
Is known if this is dedicated to a specific person in this song?
