From the wiki: “‘Love Me with All Your Heart’ was based on the Spanish-language song “Cuando calienta el sol”, written by Nicaraguan songwriter and bandleader Rafael Gaston Perez, and made famous first with Spanish lyrics written by the Rigual Brothers (Carlos Rigual and Mario Rigual). The English-language lyrics are sometimes credited to Michael Vaughn (or Maurice Vaughn) and sometimes to Sunny Skylar. Although both the Spanish and the English versions are love songs, the lyrics are not direct translations of each other. The Spanish title translates as ‘When the sun heats (or warms) up’.
“Steve Allen & His Orchestra covered the original version in 1963, peaking at #83 on the Billboard Hot 100. The following year, the Ray Charles Singers hit the US Top-5 with their English-language cover. A UK cover version, by Karl Denver, peaked at #35.”
