"El Arreglito" is a habanera composed by Sebastián Yradier, which was used by Georges Bizet in his opera "Carmen". Bizet - thinking it was a folk song - was inspired by the melody and recomposed it as the aria "L'amour est un oiseau rebelle", also known as the "Habanera". When he discovered his mistake Bizet added a note to the vocal score of the opera acknowledging its source.
