Mundo de juguete

I saw the Trivia about "Mundo DE Juguete" and would like to know what the music is when Cristina (Graciela Mauri) visits "Nana Tomasita" (Sara García) I would appreciate any collaboration. I have been looking for this song for many years and I have not found any information. When I found the mentioned Trivia, thought that this is a way to find out the name of the song or at least, to know who the performer is. This is a beautiful instrumental/mood song. I think basically it is about synthesizers and probably a little orchestra. Again, i would appreciate any support about this subject.

Thanks in advance
