This song is moving but cryptic--it's hard for me to tell what's going on. There may have been a breakup between the narrator and the person addressed in the chorus, a long time ago, though (maybe) the narrator still has feelings for the addressee--"Time it is past now and I roam free, / Is it wrong to wish you still need me?" Is the narrator someone who's left their partner (temporarily at least), but feels lost and lonely and isolated without them?
Out in the field where the lark it flies,
Over the earth where my heart it lies,
Oh how it sings when the west winds blow,
Out in the field where no-one goes.
Oh how I'm cold will you let me in,
If you could hear me speak, where would I begin,
Time it is past now and I roam free,
Is it wrong to wish you still need me,
Is it wrong to wish you still need me.
