Theme song

I don't like the film very much (although Zezé Motta, Walmor Chagas and Marcus Vinicius are great in it), but I do love the theme song by the great Jorge Ben (today Jorge Benjor). Legend says that, instead of writing the lyrics, he just put music to the film's synopsys!

Here it is: http://www.youtube.com/watch?v=-pNlv4Cn1_Y

A version was made by Milton Nascimento and Gilberto Gil almost 25 years later, but it's not really good: http://www.youtube.com/watch?v=RW8pRin2R_8
