Je cherche fortune (Chez le boulanger)
This song was written originally by Aristide Bruant, who joined the cabaret "Le Chat Noir" in 1884. That year he wrote a song "La Ballade du Chat Noir" which became a theme song of sorts for the cabaret. They published it in their weekly paper on 2 August 1884.

Over time, the song picked up numerous verses and evolved into its rather baudier modern form, mostly known as "Je cherche fortune".

This is the beginning of the original song:

La Ballade du Chat Noir
by Aristide Bruant, 1884.

La lune était séreine,
Quand, sur le boulevard,
Je vis poindre Sosthène
Qui me dit: Cher Oscar!
D'où viens-tu? vieille branche,
Moi, je lui répondis:
C'est aujourd'hui dimanche,
Et c'est demain lundi...

(Refrain)
Je cherche fortune
Autour du Chat Noir,
Au clair de la lune,
Á Montmartre!
Je cherche fortune
Autour du Chat Noir,
Au clair de la lune,
Á Montmartre le soir!

The song goes on to describe a scrape with the police, after which the narrator spends a night in jail.

The cabaret was quite famous. Verlaine and Baudelaire were not only regular patrons, but wrote verse for the weekly.
