The version of "Libera" originally presented was a ballad, but prior to the contest the arrangement was completely altered, turning it into an uptempo disco-style song. The new arrangement is said to have been inspired by the version of Bob Marley's "No Woman, No Cry" which had appeared some months earlier on Boney M's debut album Take the Heat off Me. "Libera" was noted for its overtly feminist lyrical content with allusions to topics such as contraception and extra-marital sexual relationships, which were contentious issues of the day in Italy.
On the night of the final Martini performed 15th in the running order, following Spain and preceding Finland. Martini gave a powerful performance, but at the close of voting "Libera" had picked up only 33 points (the highest an 8 from Ireland), placing Italy a disappointing 13th of the 18 entries. The Italian jury awarded its 12 points to Monaco.
