The couplet is there, searching on the theme word will get you there and should give you the poet. There is only one line of the other poem as far as I can see. A google search of the title gave me the answer.
Have at last found a poem called the themeword and it contains the four words I find in the grid. However I cannot get the name of the poet in the grid as I am an N short when I start from the initial of the Christian name. Am I on the right lines?
