Bye Bye Brasil is a Brazilian song written by Chico Buarque with music by Roberto Menescal, composed in 1979 for Cacá Diegues' film Bye Bye Brasil. The story follows a man who, through a public telephone, narrates his wandering adventures to his girlfriend as he travels across Brazil. The original recording appeared on the film's soundtrack, and because Buarque’s lyrics were longer than what the film allowed, they were finished and added during the final mix. The director even considered removing a line about a Japanese behind him, but the lyric was kept. After the film, Menescal reworked the arrangement for Chico Buarque's own release, and he also cut an instrumental version for his album Ditos e Feitos. The tune was issued as a 7-inch single around 1980 on Philips, paired with an instrumental on the B side and a track by Dominguinhos and Guadalupe on the flip. The song is associated with MPB and Forró, and it sits within the broader Brazilian Latin music tradition.
