The follow-up single, "Un angelo", peaked at no. two in the Italian charts and no. ten in Switzerland in the spring of 1976. The band continued the international success with "Dolce amore mio" which reached no. six in Italy and no. three in Switzerland. In 1977, I Santo California took part to the Sanremo Music Festival with the song "Monica", finishing third. The song quickly turned into another international hit for the band. In 1978, they scored their last top ten hit in Italy with "Manuela, amore!". After that, I Santo California's popularity decreased. The band continued to record and perform but struggled to maintain the same degree of commercial success.
