"Love Me with All Your Heart" is a popular song, based on the Spanish language song "Cuando calienta el sol", originally composed as "Cuando Calienta El Sol En Masachapa".
The music was written by Rafael Gastón Pérez, a Nicaraguan songwriter and bandleader.
SADAIC (the Argentine Society of Music Authors and Composers) also credits the Argentine composer, Carlos Albert Martinoli.
Although both the Spanish and the English versions are love songs, the lyrics are not translations of each other.
The Spanish title translates as "When the sun heats (or warms) up".
