L”I went down to the St James Infirmary,/n /

Saw my baby there,/n /

Stretched out on a long white table,/n /

So sweet,so cold,so fair,/n /

Let her go,let her go,God bless her,/n /

Wherever she may be,/n /

She can look this wide world over,/n /

But she’ll never find a sweet man like me,/n /

When I die want you to dress me in straight lace shoes,/n /

I wanna a boxback coat and a Stetson hat,/n /

Put a twenty dollar gold piece on my watch chain,/n /

So the boys’ll know that I died standing up.”;

L”the sky seems full when you’re in the cradle/n /

the rain will fall and wash your dreams/n /

stars are stars and they shine so hard…/n /

now spit out the sky because its empty/n /

and hollow and all your dreams are hanging out to dry/n /

stars are stars and they shine so cold…/n /

once i like crying twice i like laughter/n /

come tell me what i’m after.”;
