Les Valseuses

Some days ago I got introduced to some crazy and wonderful jazz recording: Tribute to Stéphane Grapelli, by Didier Lockwood & Biréli Lagrène (violin & guitar).
One of the tunes, Les Valseuses, was composed as soundtrack for the equally named film, which I watched last night. I guess it was the first time I watched that kind of movie (it's from 1974, features an unbelievably young Gerard Depardieu, and provided my initiation to French rude language) and I still don't really know what to think of it - for the moment I'm in a state of shock, laughter, and disbelief.
But the worst thing is that for nothing in the world I can get that genious tune out of my head!! So it merrily keeps jamming along in my ear.. "tada-daa-tada-da-da-ta-da-daaa.." but listen yourself!
