The song "Long Forgotten Sons" to me, is about a number of things. "Far from home on a road unknown where the vultures circle on winds that blow from northern skies that haunt these waking moments." Tim is talking about how soldiers are sent overseas(Far from home on a road unknown) and face unpredictible dangers from the terrorists.(Where the vultures circle on winds that blow).
The chorus," We are the long forgotten sons, and daughters that don't belong to anyone, And we are alone under this sun, as we work to fix the work that you've undone." This talks about us as the rising generation, having to work to fix the many problems that our predecessors have left us.
