Sometimes, after a long Saturday night of drinking, the train simply doesn’t come. That’s a fact that goes along with living in New York. Sometimes you’re drunk and tired and on the subway platform with dozens of other drunk, tired people. But sometimes, there’s also a woman with a killer voice and a dude with a guitar, and the dozens of other drunk people want to dance. And sometimes there’s just enough time before the next train for one beloved disco classic. And sometimes you have your phone handy and you’re able to capture the perfect storm of a long night, a long wait, and Gloria Gaynor.
