On the live album John introduces it as a song for Mick and Frankie. Frankie is in the song. Mick is John's brother-in-law and the song is about his personal experiences. Mick had never said anything about his time in Nam until one day, when they were alone, John asked him. He went and pulled out a stack of photos and newspaper clippings. They sat there for two days talking, crying, laughing. John then went and wrote the best song the band ever did and the most moving song I know.
