Romeo and Juliet takes place in the Italian city of Verona, a city which has a local football club called Hellas Verona. Hellas is the native phonetic pronunciation for Greece, the country from where Vangelis comes.
OK. The French for 'Yellow' is Jaune. Submarines have some kind of armour plating to protect them (bear with me here). If you put "Jaune" and "Armour plating" together it sounds a bit like Joan Armatrading, who had a huge hit with 'Love and Affection'.
