YOU SAID:
Havana, oh na na. Half of my heart is in Havana, na na.
INTO JAPANESE
ハバナ、ああ na na。私の心の半分は、ハバナ、na na。
BACK INTO ENGLISH
Havana, Oh na na. Half of my heart's Havana, na.
INTO JAPANESE
ハバナ、ああ na na。私の心のハバナ、na の半分。
BACK INTO ENGLISH
Havana, Oh na na. Half of Havana in my heart, na.
That didn't even make that much sense in English.
