In the wake of 9/11, I spent about five months in a hotel in New York City while working for MSNBC and covering the aftermath of the attack. Besides media people like myself, the place was populated with a rotating cast of Red Cross workers and assorted construction staff. This song came up quite a bit on the jukebox in the hotel's bar, a place where I spent a decent portion of my time trying to recover from what I dealt with day and and day out. It renewed my sense of fight each time I heard it -- and it still has the same effect on me eleven years later.
Here's U2's New York.
