One bit that still puzzles me even with the explanations above. Why is it Casey's last ride? Is it his last ride as in he knows he is done for in some way? Last as in he isn't going to do it again? I presume the ride is the ride on the underground - or is it? Is he depressed because he knows he is leaving her or becuase he is going home?

All academic realy I suppose - superb song anyway:-)
