Fortuleo has perfectly summed up the reason why I'm not too fond of this song, especially as a finale. I tend to prefer the "climaxing" type of last tracks to the "end credits" kind. I can appreciate the latter sometimes, provided that the penultimate song is the climax. Which Uncle Son clearly is not. What I find interesting in the lyrics is, you never know where the guy comes from. He's not fighting for a geographical identity, he's not grounded in a particular area ; it's the new lifestyle he rejects, not really the new place. Because his inner self is already somewhere else. Or, he does mourn the past, and in a sulk decides to take refuge in his imaginary United States. He's moving from his old house to a Rock'n'Roll fantasy.
