I wasn't at the London and Manchester gigs but I've read all your comments.I first saw the vids and was surprised to hear "Comme un soleil mal luné" as opening song for two reasons: first because it's a slow and sad song and second because it's in French.I think he did it on purpose. My explanation may seem naive and too simple but I think he did it to inform his fans he really is "mal luné" meaning in a bad mood as most of people who attended the gig said he was.
"je suis seul, si seul... (I'm so lonely). He has said several times that the found the French language better to write more personal things.Probably because he spent his chidhood in France. He's is ill, tired, doesn't approve some of his managers décisions, his album doesn't sell in the UK, he gets bad reviews, and yet he is at home.Many reasons could be put forward, even a row or a break up with his lover who was at the "origin" of the writing of this album..
