Gesù bambino - Francesco De Gregori
A seemingly harmless little song, almost silly, indeed; tiny tiny. However, I have always found it VERY unsettling from the first moment I heard it, many years ago. I don’t think the Prince could have foreseen what is happening in the powder keg, but certainly the piece seems to have been quite auspicious, by his standards.
P.S. And in some lines ("forgive everyone, except for someone") I think you can hear the influence of Lucio Dalla, who was at the time engaged with him in the "Banana Repubblic Tour".

From me (and not just me, mind you) seen back then, what can I tell you!
