So I had the opportunity to show off, had a lot of friendly customers, one guy gave me a tip that was actually a 2 euro coin (!), and two customers kissed me on the cheeks.
The support band was Amandine Bourgeois, a TV reality singer (she participated in a kind of French X-Factor). When she was in the show, she had a rather 'rock' and cool look. But on stage, she had high heels and a mini and skin-tight pink dress. Awful!
A few people left while she was covering 'Crazy' by Gnarls Barkley, telling me 'she's driving us crazy!'

Then: Johnny Hallyday. Well, you probably never heard of him, but he's supposedly the 'French Elvis' (even though he's not). But in France, even if you don't listen to his music, you know it, and you know the lyrics. He's been THAT popular for 50 years. He's our Beatles.
So the show was not as spectacular as loads of other ones he did in stadiums etc, but still, it was impressive (especially for the rest of my team) to see the audience singing and dancing and screaming his name.
I still think that he used his voice much more better when he sings balads than when he's 'rocking'. And I still think he's a bit of an idiot, especially as he said 'It's good to be at the Royal Albert Hall, it reminds me lots of things' while he's never been there before. And it's obvious he says the same things at every single concert he perfoms. But still, I was very curious to see him as, as I said, he's an icon. And it was a very interesting night for the whole team!
