Deschamps was born with congenital deformities of all four limbs; he is missing both his left arm and right leg, and has only two fingers on his right hand.

For his second album, 2001's Différent, he donated a portion of the profits to Montreal's Centre hospitalier universitaire Sainte-Justine, and subsequently became a spokesperson for the province's Semaine des personnes handicapées.

He subsequently recorded two songs for the soundtrack to Denise Filiatrault's film Alice's Odyssey (L'Odyssée d'Alice Tremblay) and a duet with Lynda Lemay, and mounted a successful concert tour in France.

In an interview with fellow disabled person Elizabeth, he cites Metallica, AC/DC and PATOFFE as his greatest musical inspirations.

He began the performance by discussing his history of smoking, and after declaring that he was now a non-smoker he said "Boy, do I feel good" and danced on stage.
