Top Italian pop artists have always dabbled in some Spanish, going all the way back to Domenico Modugno and then in the 70s Nicola di Bari, who became a major star in Latin America after his Sanremo wins and appearance at Eurovision. By singing in Spanish, the potential audience jumps 10x given the number of Spanish speakers in the world compared to Italian so it makes a lot of commercial sense, especially with a large Spanish audience even in the United States; Laura Pausini, Eros, and Nek have all performed to majority Spanish-speaking audiences in the US. Some singers have become even bigger stars with Latin audiences than in their homeland such as Franco Simone.
In the 80s, the list of artists that decided to give Spanish a try is a who’s who of 80s Italian pop including Toto Cutugno, Pupo, and I Ricchi e Poveri – and even Nino D’Angelo got into the act.
