As I was riding the subway the other day, one of those special moments occurred where a street performer entered the car and gave a little show for a captive audience who were less-than-captivated. With a guitar, the lady started to sing “Tomorrow” from the musical Annie, and it suddenly dawned on me that there are just certain showtunes that I don’t ever need to hear again, especially while trapped on a delayed, uptown C Train. “Tomorrow” and its cloying optimism is one of them.
