I would have to agree with the original idea posted that it is about a long distance relationship (in a sense) and that people seem to read too much into it. I don't think that he is still with the girl who is the antecedent for "she". I'm thinking they probably broke up because he's always gone. "I think it's pretty sad how we're singing the same songs, humming the same songs." This is referring to that well-known cliche that loved ones are united by certain things, like "we're both looking at the same moon right now", for example. "I'd do anything to know she's waiting for me." She's not waiting for him but he feels like she should be because they're supposed to be together. I agree with the rest of the arguments though, such as "From the road we sit and watch it pass by" being that they are on tour and such.
