In an interview for the 2012 documentary
Hoje É Dia de Luiz, João Silva said that he and Luiz Gonzaga came up with the idea for the song when they saw two "Europeans" wearing "little skirts and bagpipes" on a beach. Some theorize that Silva and Gonzaga mistook them for
Cossacks, a people from Eastern Europe, as it is more likely that the two individuals were wearing traditional
Scottish attire. In the song, the singer says that he dreamed he was at the fictional nightclub Cossacou in
Moscow, where he started dancing a 'Russian pagode' (the trepak) and compares the dance to
Pernambuco's
frevo. The song was originally released in 1947 as an instrumental, however, it only became a hit in Brazil in 1984, when it was rerecorded with lyrics by Luiz Gonzaga and João Silva on the album
Danado de Bom. == Other versions ==
