This afternoon in the 51st Street subway station, there was this bowlegged white guy with a moustache and an acoustic guitar singing Against the Wind on the other platform. It was quite beautiful, and as he was singing, in the middle of the song, a black guy carrying a newspaper stopped in front of me and started singing harmony with him, across the tracks. It was unspeakably beautiful, and even after the newspaper guy walked away, the moustache guy kept singing louder and even more beautifully until the train came.
