After attaining some success in Spain, TNT moved there in 1963. They went as far as representing the country in the Eurovision Song Contest 1964 in Copenhagen, billed as "Nelly, Tim and Tony". Tony stated once that the group was handpicked by the powers that be behind TVE, the Spanish state television, to substitute that year's winners in the Spanish classification round, Michel and Teresa María, popular Spanish singers of the time. TVE toned down their normally dynamic act for the contest, in which they sang what was originally a slow ballad, ""Caracola"" (written by Spanish songwriter Fina de Calderón). Tony and his siblings suspected that this was a disaster waiting to happen. Disappointed by their twelfth-place finish in the competition, and the subsequent reaction in Spain, their willingness to tour and record there diminished with time. They moved back to Argentina in 1965. Tim eventually left the group in 1966 and returned to his native Italy to become a concert promoter.
