This is from the classic animated Lucky Luke movie, "The Ballad of the Daltons".
Now, bear with me, this is the original undubbed French version of this movie.
Anyway, I adore this scene! Great timing, the animation was pretty decent for the mid-70s and the music's just perfect.
I just love the way it gets crazier over the arrival of the train the Daltons are planning to attack.
Check it out!
I didn't upload this one, so I can't offer you direct translations over the image. But it should be pretty understandable even for non-French speakers.
