Andorra participated in the Eurovision Song Contest 2007 with the song "Salvem el món" written and performed by young Andorran punk-rock band Anonymous, consisting of band members: Guillem Gallego, Niki Francesca and Alejandro Martínez. The band was internally selected by Andorran broadcaster Ràdio i Televisió d'Andorra (RTVA) in a process called Projecte Eurovisió for the 2007 contest in Helsinki, Finland. The internal selection ended with a total of 82 songs having been submitted to RTVA. These entries were whittled down by the broadcaster to determine the fourth Andorran representatives. Anonymous were announced as the Andorran representatives on 15 January 2007, while the song was presented in a special gala show on 1 March 2007.
