Wiki: "Smoke Gets In Your Eyes" is a show tune written by American composer Jerome Kern and lyricist Otto Harbach for their 1933 operetta Roberta. It was performed by Irene Dunne for the 1935 film adaptation, costarring Fred Astaire, Ginger Rogers and Randolph Scott. It has been covered by numerous artists, possibly the most famous of which was recorded in 1958 by the doo wop group The Platters, which became a number one hit on the U.S. Billboard Hot 100. ... The song has been featured in several films, including George Lucas's American Graffiti (1973) and much later in the 2004 Golden Globe-winning film Being Julia, directed by István Szabó. The Platters' rendition is the centerpiece song to Steven Spielberg's 1989 film Always, and features significantly in both the plot and soundtrack of Hou Hsiao-Hsien's 2006 film, Three Times. It has also appeared in Rainer Werner Fassbinder's "The Bitter Tears of Petra von Kant". "Smoke Gets In Your Eyes" is the title of the 2007 pilot episode of the AMC original drama Mad Men.
They asked me how I knew
  My true love was true
  Oh, I of course replied
  Something here inside cannot be denied 
They said someday you'll find
  All who love are blind
  Oh, when your heart's on fire
  You must realize
  Smoke gets in your eyes
So I chaffed them and I gaily laughed
  To think they could doubt my love
  Yet today my love has flown away
  I am without my love
Now laughing friends deride
  Tears I can not hide
  Oh, so I smile and say
  When a lovely flame dies
  Smoke gets in your eyes
  Smoke gets in your eyes
