The poem
Looking up at the stars, I know quite well That, for all they care, I can go to hell, But on earth indifference is the least We have to dread from man or beast. How should we like it were stars to burn With a passion for us we could not return? If equal affection cannot be, Let the more loving one be me.
Admirer as I think I am Of stars that do not give a damn, I cannot, now I see them, say I missed one terribly all day.
Were all stars to disappear or die, I should learn to look at an empty sky And feel its total dark sublime, Though this might take me a little time.

Crap poem, I mean it doesn't rhyme or anything. Is "copyright holder" a metaphor? Bloody obscure!
Joh, the poem does infact rhyme. Maybe you are confusing it with another poem. But either way, great poetry does not have to rhyme.
