This is a very beautiful song, but sad. I'm thinking she's singing about her friends that moved away to big cities, such as Philadelphia and NY, for bigger and better careers and lives. But she notices that as they get wrapped up in their lives, deep down, there's not as happy like they were when they all lived in the same town (i.e. "when the shows are over, don't know where to go.") She's hoping that they'll be happy again, and that they won't forget about her or how much fun they had together.
