"Caracola" (Spanish pronunciation: [kaɾaˈkola], "Conch") was the Spanish entry in the Eurovision Song Contest 1964, performed in Spanish by the trio Tim, Nelly & Tony, better known as Los TNT. The entry marked two firsts in the Contest for Spain; it was the country's first Eurovision entry not to be sung by a soloist and also the first occasion on which the Spanish entry was sung by performers of Latin American origin. Los TNT was composed by three siblings of Italian-Uruguayan descent; Edelweiss "Tim" Croatto, lead singer Argentina "Nelly" Croatto and Hermes "Tony" Croatto, all born in Udine, Italy but raised in La Paz, Uruguay and Montevideo, Uruguay.
