In the song "Graceland", how old is Paul Simon's traveling companion, a child from his first marriage?

"Graceland" is the seventh solo studio album by singer-songwriter Paul Simon. It was produced by Simon and engineered by Roy Halee. The album's release came in August 1986, by Warner Bros. Records. "Graceland" is the title song of the album and features vocals by The Everly Brothers.

The lyrics of the song "Graceland" deal with the singer's thoughts during a road trip to Graceland after the failure of his marriage. Actress and author Carrie Fisher, Simon's ex-wife, said that the song referred in part to their relationship. Simon said that the specific line in the song about the nine-year-old traveling companion is a reference to his son Harper. Harper was born to Simon and his first wife Peggy Harper in 1972.

Graceland mansion, the famous home owned by the legendary Elvis Presley, is a mansion located in Memphis, Tennessee. Concerning the album, Simon told "Rolling Stone Magazine', "Graceland" is a political statement in itself. I never said there were not strong political implications to what I did. I just said the music was not overtly political. But the implications of the music certainly are. And I still think it’s the most powerful form of politics. People get attracted to the music, and once they hear what’s going on within it, they say, ‘What? They’re doing that to these people?'”

The album won the 1987 Grammy Award for the Album of the Year. It also sold over 15 million copies all over the world to become the most successful album of Simon’s entire career.
