• All Time Low don't want to forget the fans and venues from their early days.
  
  So long, so nice to know ya
  Nice to know ya
  I'm sorry to say
  We can't go back to yesterday
  
  The band said the song is a dedication to the people and places that made them who they are today:
  
  "This one's for the dance halls, the dive bars and the 100 kids we used to play for at the Ottobar every other weekend. It's a tribute to our roots and the history of a band that comes up in a small-town with a die-hard group of friends who all want something greater. It's an ode to the late nights, filling up the van with half a tank of gas so we could leave for the next show before someone got jumped in the wrong part of town. Getting into Tampa at 3am and crashing on someone's floor, saying thanks with a 30 of Coors Light and never seeing that face again.
  
  This is a dedication to all the places we've been that made us who we are today, the sea of sweaty hands that raised us up in low-lit clubs across America on our first tours, and all the people we owe these stories to; Nice to know you, see you 'round."
• Directed by Pat Tracy, the music video was shot at All Time Low guitarist Jack Barakat's Baltimore-based bar, The Rockwell. We also see the band going around and leaving roses at venues they've played at in the past.
