I'm in Scotland now, dear mother, in a place called Craiglockhart,
A refuge for tired warriors whose nerves are torn apart.

Next week I'm going to get the train back to old London,
Then I ship to France because the war is still going on.

Rhymes just as well.

Craig-LOCK-urt, folks. Possible rhymes: pocket, rocket, locket, docket, socket, though they all leave out the rhotic "r". Even "...whose nerves are buggered" would be better.
