Here's the first sentence from one of my favorite books by Clyde Edgerton, Killer Diller.
"Vernon Jackson sits on the side of his bed in his white jockey undershorts - which have mostly separated from their waistband."

These are the last three lines of the book:
"The bus slows for a turn-off, jostles Wesley. He awakes, looks around, reaches for some popcorn in the bag from Phoebe's lap. "I want some," says Vernon, reaching his hand over Wesley's shoulder.'

Clyde Edgerton is not only a brilliant writer, somewhat in the feel of Flannery O'Connor, but he is a folk musician and wrote a song that served as the title for my favorite book of his, Walking Across Egypt. He has at least one CD out.

And yes, the last line often is the bow on the ribbon on the package of a song. It wraps up the whole song.
