The collection, Du luxe et de l'impuissance, is made up of articles and editorials commissioned from Jean-Luc Lagarce by theatres and by magazines. These writings read like extracts from the personal diary of a demanding, clear-sighted man of the theatre. These texts and certain characters taken from Nous les héros and Music-hall have given rise to Paroles d'auteurs, folies d'acteurs ou le cabaret de leur vie (Writers' words, actors' follies or The Cabaret of their Lives).

The songs and the music composed by Matthieu Dalle for this show respond to the music of the different shows directed by Jean-Luc Lagarce and Olivier Py in which Irina Dalle performed.

This show therefore, has a particular history, that of an actress who re-makes the journey of the theatrical adventures she has experienced and her encounters with the men of the theatre to whom she pays tribute.

Paroles d'auteurs, folies d'acteurs ou le Cabaret de leur vie is a musical journey in the life of two music hall artists, a singer and a double bass player, who have spent their lives together on the roads, from town to town, from church fete to village hall. On two wooden pallets, painted blue, which suggest a raft drifting on a tranquil or stormy sea, they sing their small world lost in the great one. The journey of their life as artists unfolds like a cabaret, "The Cabaret of their Life": the dressing rooms, the trains, the hotels, the deals of every kind, the cold, the misery, the threats of war, the dreams of glory and the disappointments, but also the questions which suddenly appear in the middle of eating an old sandwich: questions on their art, the theatre and the Music Hall, on the place of artists in society, the technical problems encountered at the village fair. But also and especially the stage, the instant of the scene, when suddenly the instant of grace occurs, that unhoped-for moment when time stands still. For this instant of eternity, these two are ready to put up with everything, to sacrifice their life, to set off again, starving, on the roads, in the quest for another magic evening. But is it a sacrifice? The singer can only love and live on the stage. The double bass player sings only of Love. She has thrown herself completely into her art, she has burned up her life on the boards, in her quest for beauty, for the sublime. He watches her burn herself out without being able to stop her course, "love in a little house in the country", she won't have it. This evening, they are back on their raft again, for a new journey.
