As I am listening to Ghost in the strand, followed by Giacomo's Blues (got some songs sorted alphabetically), I remember that I always wanted to ask the group about these 2 songs:
 
Any information why these 2 different versions exist, and how Sting came up with the different name?
Maybe he needed a song also for Giacomo, on his way to dedicate one song to each of his kids ;-)
