Hidden away on the official site is the music video for "Lost in Berlin", the English version of Berlin! Check it out by clicking here, then selecting "Videos". The player at the bottom will automatically start Lost in Berlin (you may need to pause the audio that's streaming though, on the top left of the screen).
The lyrics to Lost in Berlin are in my comment below. (with thanks to the wonderful fans on Christophe's forum, who helped transcribe them as best we could).
