Na verdade a voz do aqua sempre foi uma farsa. Essa vozinha fina da cantora e esse vozeirão do cantor é tudo estúdio. Na apresentação ao vivo a farsa acaba e isso fica bem claro.

She's 50 here, when the song was recorded she was in her 20s. Considering the voice she uses in Aqua is super unnatural and high pitched, I'm not surprised it's a lot harder to maintain with age. Also I'm not exactly a vocal teacher or anything but if the voice she uses was actually done using proper singing technique, I'd be shocked. I will say, at the concert she was definitely struggling with a lot of songs and this was one of them, some of the other songs she sounded a lot better though.

@@dragonlamp1414 or maybe she just wanted to change it up a bit? Be more ditzy, bimbo using a more girly voice? Commending them on actually singing live. That's very rare.
