"Plus grandir" means in English "Keep Growing".
"Plus grandir" is the first song written by Mylene Farmer.
It was released twice: first, on 25 September 1985 in a studio version as second single from Farmer's debut album Cendres de Lune, then on 12 May 1990 in a live mix version as second single from the live album En Concert.
For the live version, a video of the 1989 tour was made with new images from "Plus grandir"'s performance and choreography.
While the 1985 studio version did not reach the French Top 50 Singles Charts, the 1990 live single had a short running: it stayed on the chart for seven weeks, from 19 May to 30 June 1990, peaking at number 35 on 16 June.
