Lyrics:

I should care, I should go around weepin'
I should care, I should go without sleepin'
Strangely enough I sleep well, 'cept for a dream or two
But then I count my sheep well
Funny how sheep can lull you to sleep

So I should care, I should let it upset me
I should care, but it just doesn't get me
Maybe I won't find someone as lovely as you
But I should care and I do
