Yes, that's one of many songs he claimed. And according to several sources, he is given credit for that song. He's also known as the writer of this song:

HALLELUJAH! I'M A BUM
As recorded by Harry McClintock (as "MAC") on Victor 21343-B, 1928. [Listen at The Internet Archive.]

Rejoice and be glad, for the springtime has come.
We can throw down our shovels and go on the bum.

CHORUS: Hallelujah! I'm a bum. Hallelujah! bum again.
Hallelujah! give us a handout, to revive us again.

The springtime has come, and I'm just out of jail,
Without any money, without any bail.

I went to a house and I rapped on the door,
And a lady says: "Bum, bum, you've been here before."

I like Jim Hill; he's a good friend of mine.
That is why I am hiking down Jim Hill's main line.

I went to a house and I asked for some bread,
And a lady says: "Bum, bum, the baker is dead."

Why don't you work like the other men do?
Now, how can I work when there's no work to do?

Why don't you save all the money you earn?
If I didn't eat, I'd have money to burn.

I don't like work, and work don't like me,
And that is the reason I am so hungry.

CHEERS, Bob Nelson
