I had forgotten this song…the theme song of The Luc Besson’s epic film Joan of Arc…I wrote the lyrics and sang , Eric Serra wrote the music. Today, when I have become a sort of Joan of Arc myself, this song becomes very relevant….every word, like a knife to the heart. I just hope I don’t end of like she did… The Messenger: The Story of Joan of Arc, from Luc Besson was released in 1999. Noa and Eric Serra have created the original soundtrack’s song “My Heart is Calling”. In 1429, the French teenage girl, Joan of Arc, announced she would defeat the world’s greatest army and liberate her country.
