CARELESS LOVE

I'm lonely, lonely tonight,
Nobody cares no more for me,
He has gone from me to another little girl
And won't come back no more,
Love, oh love, yes careless love,
Can't you see what careless love can do?
It has broken the heart of many a poor girl
And I'm sure it will break this heart of mine.

Sometimes I think that I will leave
And never come back any more,
But when the time comes for me to start
I will not worry any more.

Go hand me down my old valise,
And bundle up my dirty clothes,
And if my momma asks about me
Just tell her I'm sleeping out of doors.

Goodbye, goodbye, now we must part,
I know indeed it'll break my heart,
But since you care no more for me
Just go to the one that you love best.

Sung by Miss Grace Hahn, Fayetteville, Arkansas, 1941. With music.

CARELESS LOVE B

Come my little pink and tell me what you think,
You're a long time making up your mind,
I truly understand that you love another man,
And folks tell me that your heart ain't mine.

I don't like to work, but I love to keep time,
-------------------------
I do love to hear the dinner horn blow,
But I feel like I got no home.

Hand me down my suitcase and all my dirty clothes,
I'm a-going away for to stay,
And if she comes to see me while I'm gone
Just tell her I'm a-sleeping in the clay.

One white shirt is all I got,
One dollar is all I crave,
I didn't bring nothing to this here world,
And I won't take nothing to my grave.

Lance Howard, Webb City, MO, 1923. Like the above but lacks the "Careless Love" refrain.

CARELESS LOVE

Love, oh love, oh careless love (2 times)
It's love, oh love, oh careless love,
You see what love has done for me.

It's a shame we ever met (3 times)
For those good times we'll never forget.

Now my money's spent and gone (3 times)
You pass my door a-singing a song.

Oh I love my mamma and my papa too (3 times)
But I'd leave them both and go with you.

Oh I cried last night and the night before (3 times)
Going to cry tonight, then I'll cry no more.

Ain't this enough to break my heart, (3 times)
To see my man with another sweetheart?

Oh it's done and broke this heart of mine, (3 times0
And it'll break that heart of yours sometime.

Mrs. Lillian Short, Galena, MO, 1942.

The above all from Vance Randolph, vol. 4, pp. 306-308.
