In the film, the character, Micky, while riding in the back seat of a car, sings a song. The song's chorus seems to begin with:

Todo vida cantamos

followed by a list of other things that the song says "we" spend our lives doing.

I very much liked this song; but was unable to capture enough of it in my memory. From the context of the film, I am guessing that this may be a revolutionary song, perhaps germane to the politics of Panama. But maybe not. Does anyone know this song?
