Cover art for Kashka from Baghdad lyrics by Kate Bush

Indeed this song is about a gay male couple. Kate sings as Kashka's neighbor and she sees him happy with another man and she envies them because she can't have seem to have the happiness that they have. She wants to get to know them. What does "a la lune" mean?

And the neighbor feels a little guilty spying and feeling jealous.
