I'm searching for a Latin summer song with a girl and a boy repeating each other. The boy has a low voice. The song is mid tempo/dance. It has a Brazilian/Portuguese touch... ...maybe Spanish but not sure. I heard it from far away on a festival in France this weekend (Garorock - 2018). I didn't hear the words, I'm not totally sure they repeated exactly each other, but the melody was repeated exactly between the 2 singers! Hope someone can help! Thanks!
