Vanusa Santos Flores (22 September 1947 – 8 November 2020; Portuguese pronunciation: [vaˈnuzɐ]) was a Brazilian singer, linked to the Jovem Guarda movement.

[2] In March 2009, she sang the Brazilian National Anthem at the Legislative Assembly of São Paulo.

Accompanied by a couple of musicians, she committed many lyrical mistakes during her performance and ended up singing out of rhythm.

Attenders of the show tried to prevent her from continuing by applauding before the end of the presentation, and she kept on singing until the presenter eventually thanked Vanusa for her performance, with her still singing on the background.

[3] She later stated that she was confused because of the medicine she took that morning for her labyrinthitis, and said she would hire a lawyer to have any suggestions that she was drunk removed from the internet.
