Task: Question Answering
Input (English): passage: The lyrics and melody of the song were written by Édith Piaf herself, but the melody was said officially to have been composed and registered by Louiguy only, since at the time, due to the stringent registration requirements of SACEM, Piaf did not have the necessary qualifications to be able to copyright her work with SACEM. Piaf offered the song to Marianne Michel, who slightly modified the lyrics, changing ``les choses'' (``things'') for ``la vie'' (``life''). In 1943, Piaf had performed at a nightclub/bordello called ``La Vie en Rose''. Initially, Piaf's peers and songwriting team did not think the song would be successful, finding it weaker than the rest of her repertoire. Heeding their advice, the singer put the song aside, only to change her mind the next year. The song was performed live in concert for the first time in 1946. It became a favorite with audiences. ``La Vie en rose'' was the song that made Piaf internationally famous, with its lyrics telling about the joy of finding true love and appealing to those who had survived the difficult wartime.
 question: is la vie en rose a love song?
Output (English): Yes
