For the ones who don't understand French very well I've just translated what Mika says at the beginning of the concert, before he sings Relax:
"This date creating stress, the 14th of February, it is a BIG romantic event. You are my reward for all the sh***y 14rh of Feb I've had in my life!
On the 14th of Feb, you meet someone, it has only been a couple of days youve met each other. A coffee break at your place, yes why not.. "coffee".., a small drink maybe, you're about to kiss each other and at the last moment you say "no", because I want to know you. So the person say "ok..", and you say "no, you're not going to remove your clothes, you're going to sing, because if you sing I'll understand much better who you are than if you remove your underwear","oh really","singing reveals much more than panties"
As it is the 14th of Feb and that we're going to spend a very intense evening together, I think it has come the time to get to know each other.
So Strasbourg... This is my lover voice, I reveal it to you for the first time, don't get off your clothes, sing with me."
Tell me if you would like any other translation!
Thanks @Anna Ko Kolkowska and @mellody for the videos and reports, great memories of a wonderful evening!
