I guess I'm in the best position to tell you:
This shouting at the end of the album is real. I used to live in a quite rough neighborhood before, and one night I was working on the "French Cancan" album, my windows were open...it was past midnight, and there was this drunk guy who began to yell, down the street...fortunately my mike was plugged, I just had to record the whole scene whithout being seen...
in fact it lasted about half an hour, but I kept the most interesting parts...at one moment, you can hear my neighbour, an old woman who tells she would like to sleep !!!
The expression the drunk guy uses the most is "Ta gueule", which means "Shut the fuck up" in french...he says it 27 times ! Everyday I thank god that he couldn't notice the fact that I was recording him !
We found it would be funny to put it as a ghost song (of course I moved in a more quiet place !)....so be careful of what you say...I may be hiding somewhere with my microphone...
