This song is the opening theme of the 1977 children's television series based on the renowned children books of the same name by Brazilian author Monteiro Lobato.
The same song was also used on the 2001 series, e.g.: www.youtube.com/watch?v=i9RbBcDTRAI.
The choice of Gilberto Gil as a singer and composer was a stroke of genius, as his natural quirkiness perfectly suits the subject matter of the books.
