Walk the Line Easter Egg - Johnny's Fan Mail

When Johnny Cash is reading fan mail towards the end of the film (around the 1:52:00 mark), he unfolds a typed letter from an inmate at Folsom Prison.

Following that, he opens a hand-written one that begins, "Dear Mr. Cash - My name is Glen Shirley."

It is only shown for a moment, but it happened to catch my eye because Glen Shirley is credited by Cash on the albumn, "Johnny Cash at Folsom Prison" for writing the song "Greystone Chapel" (track 19).

As Cash says on the record, "This (Greystone Chapel) was written by a man right here in Folsom Prison, and last night was the first time I ever sang this song. This song was written by our friend Glen Shirley, and we hope we do your song justice, Glen."

Anyway - Just thought the film worked that illusion in there in a neat way.
