This is a strangely written story. I don't get the point of hiding who the person is until the end, it's not like keeping them a secret changed how I felt about their tale. spoiler, since that's how this article is written Do they think I'd go "oh, who cares about Elvis' grandson?" More likely people wouldn't know anything about his grandson and back out after the first line.
I’m no particular fan of Elvis (have gone to Memphis several times and never even considered visiting Graceland), but I guessed it was Elvis’ grandson and spent 20% of my attention trying to confirm or deny that.
IMO, it’s not a particularly useful artifice.
