Distance Blues and Theory

Where you to cross the world my dear?
To work or love or fight
I could be calm and wistful here
And close my eyes at night
It were a sweet and gallant pain
To be a sea apart
But oh, to have you down the lane
Is bitter to my heart

Into love, and out again
Thus I went, and thus I go
Spare your voice, and hold your pen
Well and bitterly I know
All the songs were ever sung
All the words were ever said;
Could it be, when I was young
Some one dropped me on my head?
