Songfacts®:

• Longtime Mark Ronson collaborator Miike Snow's Andrew Wyatt added his vocals and songwriting talents to this track. Ronson told The Guardian: "Andrew had this bassline (from an xx remix that he never finished) and just started singing the lyrics off the page. We added some chord changes and it was pretty much done."
  
  "This is one of my favorite pairing of lyrics/song/performance on the album," he added. "If I could sing like Andrew, I would stay home and serenade myself all day."
• The majority of Uptown Special's lyrics were penned by Michael Chabon, the Pulitzer Prize-winning novelist behind The Amazing Adventures of Kavalier & Clay. Ronson told The Guardian about the author's contribution to this track: "Michael had these lyrics fully formed," he said. "He was really into the expression 'heavy and rolling' that NYC hire car drivers use to signify to the base that they have their passengers and are on the job."
