"Same Old Lang Syne" is a song written and sung by Dan Fogelberg from his 1981 album The Innocent Age. The song is a narrative ballad told in the first person and tells the bittersweet story of two long-ago lovers meeting on Christmas Eve. The melody phrase at the beginning of each verse is taken by Fogelberg from Tchaikovsky's 1812 Overture. During its debut, the song peaked at #9 on the Billboard Hot 100 Chart and is now frequently played during the holiday season and is integrated with traditional Christmas songs.
The narrator is reunited with an old flame at a grocery store on a snowy Christmas Eve. She doesn't recognize him at first glance and when the two reach to embrace, she drops her purse causing them to laugh until they cried; this moment foreshadows a bittersweet departure. They eventually decide to have a drink somewhere, but are unable to find any open bar. Settling on a six-pack purchased at a liquor store, they proceed to drink it in her car while they talk.
The pair toast innocence of the past as well as the present, all framed in the song's chorus. The subsequent verse describes the two pushing through their initial awkwardness and discussing their current lives. The lover went on to marry an architect and is seemingly content with her life, though it is implied that she married for security instead of love. The narrator then says that as a musician he loves performing but hates touring.
After a second toast, the conversation runs its course. They exchange their goodbyes and the woman kisses him before he gets out of the car. As she drives away, the narrator contemplates the good times they'd had long ago, hence the meaning and reference to the song's title: Auld Lang Syne. At the song's most bittersweet moment, the narrator experiences yet another "auld lang syne," as he is reunited with "that old familiar pain" from their break-up at an earlier time in their lives. The snow that surrounds him then turns to rain, signifying a happy time turned quite melancholy.
The song ends with a soprano saxophone solo by Michael Brecker based on the melody from the original Auld Lang Syne.
Given the first person narrative of the song, many listeners have frequently wondered how valid the song really is. Fogelberg himself had confirmed on his official website that the song is indeed autobiographical:
After Fogelberg's death in 2007, the Peoria Journal-Star reported that the girlfriend referred to was Jill Greulich (formerly Jill Anderson) who attended Woodruff High School with Fogelberg. 
"Same Old Lang Syne" is frequently played on radio stations (particularly those having oldies formats) during the American holiday season. The song begins mentioning Christmas Eve and ends with the acknowledgment of snow, commonly associated with the Christmas holiday in U.S. popular culture. Apart from the initial (and final) reference, there is no further association with the holiday or holiday season. However, since the song's release, both the reference in the title and the musical quote of Auld Lang Syne (traditionally sung on New Year's Eve) as the epilogue have encouraged the song's popularity during December.
