[1][2] Yvette Guilbert experienced early success singing Xanrof's songs at Rodolphe Salis' cabaret Le Chat Noir.
Born in an bourgeois upper middle class environment, with his father a wealthy physician,young Leon Fourneau was inclined to a literary and poetry career, but his family insisted on him graduating (Baccalauréat) and taking up further éducation (he obediently undertook successful law studies and registered at the paris bar, aged 23), but he still felt inclined to song and opérette writing.
The Xanrof alias was a measure of appeasement towards his family and the bar authorities as léon Fourneau kept writing and publishing songs for cabaret singers.
The cab-ride was what was termed a "course d'alcôve" (lovebed-ride),a not unfrequent instance in "Belle époque"Paris where illegitimate couples enjoyed "comprehensive flirtation" in the intimacy of a cab (At least two short humoristic tales by Alphonse Allais harp on this particular theme).
In this song a cuckolded old man walking in a Parisian street hears kisses, moans, and his wife's voice coming from inside a suspiciously rolling and pitching cab.
