The success of "Eres tú" was not limited to just pop or Spanish music radio. In 1976, a guitar instrumental by country singer Sonny James reached #67 on the Hot Country Singles chart. In 1977, Tex-Mex country singer Johnny Rodriguez – who had earlier success with mixing English and Spanish lyrics in his songs – recorded a cover version and released it to country radio. The song peaked at #25 in the fall of 1977 on the Hot Country Singles chart.
