Some tracks if these exist on the LP of 1963 have been omitted on the later CD. For example on the CD M Cobrinha Verde only sings on track 2. What we have are the 7 tracks and among these are not tracks 4 (Angolinha - Sings Cobrinha Verde), nor 7 (Riachão do Diabo - Sings Traíra), nor 8 (Angolinha Miudinha - Sings Cobrinha), nor 9 (Guarani - Sings Traíra).
The back cover doesn't list Iúna nor Seqüência de Ritmos.
On the track 7 (Seqüência de Ritmos) who leads the playing and announces the names is probably M Gato Preto.
