A lovely song. John finally recorded it on last year's wonderful The Company You Keep.
That would be correct sir, I have a copy of John's album.
If I remember right, your explanatory paragraph was lifted from the liner notes of David Wilcox's Home Again.
Correct again, I think I prefer the Wilcox version.
I also have a studio version by Edwin McCain ( without Jewel ) that is very well done, he decided to change the title for some reason to "A Prayer To St. Peter".
