This poem, taken from A. E. Housman's collection The Shropshire Lad, explores the idea of nostalgia and growing old, and was the inspiration for the tragic and touching Dennis Potter play, Blue Remembered Hills.

Into my heart an air that kills

Into my heart an air that kills
From yon far country blows;
What are those blue remembered hills,
What spires, what farms are those?

That is the land of lost content,
I see it shining plain,
The happy highways where I went
And cannot come again.
