One song One song

One song I have but one song

alone!

One song only for you One song only for you

You must be very lonely. Yes, I am very lonely.

She looked lonely.

All alone,

Yes, alone

One song

I'm lonesome.

Very lonely.

I was lonely.

I'll be lonely

I was alone.

You were alone.

I'm lonesome.

I was not lonely.

The ant isn't alone.

With friendsmy candle wax!

alone with God!

Is she alone?

Why so triste?

There is lonely I am.

I'm not alone.

Now I'm alone.

I looked at you, you were alone, working.

Miss Lonelyhearts.

Alright, fellows, let's try it once from the beginning.

Do what?

Why not goddess?

My mother is alone, too.

Will you leave her alone?

Are you alone?

I get so lonely.

Gets lonesome here.

I'm awful lonely.

I know you're lonely.

All alone, that child?

Leave you here all alone?

You're here alone?

They'd always be alone, if not for me.

Am I not alone already?
