Two favorite songs about nostalgia

With my high school class reunion on the horizon, I'm thinking today about two favorite, nostalgic sets of lyrics.  Chicago's "Old Days" appeals to me with its optimistic melody and specific imagery.  (i.e.  "Summer nights and streetcars take me back to a world gone away.")  It also does an effective job in showing how the past feels like it was so long ago and yet so recent.  Al Stewart's "Time Passages," in contrast, conveys a wistful sense of loss in its lyrics.  (i.e.  "There's something back there that you left behind.")  At the same time, however, it's comforting to hear Stewart sing, "I know you're in there; you're just out of sight."  It brings to mind George Eliot's quote, "Our friends are never dead to us, until we have forgotten them."  It's a great way to think and live, actually--honoring the memory of the dearly departed by keeping the good memories alive and reminding ourselves that whatever positive attributes they brought to our lives can still be recalled and practiced today.
