The boy who played music with a dog...

I remember when I went to Lisboa, having seen a little boy with an instrument and a little dog. Exactly like in this movie. I think the story is known, because the next day, he was in first page of newspapers, and it mustn't be a coincidence if the exact copy of this situation is in the movie.

But do somebody know if it's the same boy, if Monteiro engaged an homeless boy of Lisboa? (but it was in 1999, and the movie is from 2003, maybe he would be taller...)
