Fado puxavante (traditional fado)

This traditional fado's composition has been alternatively attributed to Joaquim Campos, Júlio Proença, and Pedro Rodrigues. As early as the 1940s, doubts were already being expressed in print about its authorship. According to fado researcher Nuno Siqueira, this composition should be considered traditional, as it must be older than any of these composers' versions of Fado puxavante.
