I know it: it's l'allumeuse by les sans culottes. You can hear it at the link given. It's a great song I spent a long time trying to find. Enjoy! Email my if you need more help.
> I saw I Spy and Harry Potter in the theatre this weekend and before them there was a commercial for Hewlett Packard (for a camera I think) that was of a girl taking pictures of Paris and printing them and putting them up. It had a really fantastic French song to it -- does anyone know what it is?
