I was a bit surprised not to find this song in the database, despite entering it by [name] and several [key phrase] checks:

PASSING THROUGH

I saw Adam leave the garden with a suitcase in his hand,
I said "Now you're out, what are you gonna do?"
"Plant some crops and pray for rain,
Maybe raise a little Cain,
I'm an orphan and I'm only passing through."

Chorus:
Passing through, passing through,
Sometimes happy, sometimes blue,
Glad that I ran into you,
Tell the people that you saw me passing through.

I asked Jesus on the cross on the hill called Calvary,
"Do you hate mankind for what they did to you?"
He said, "Speak of love, not hate,
Got to go, it's getting late,
I've so little time and I'm just passing through.

I spoke with General Washington in the snow at Valley Forge,
I asked him, "Why will men go through what they go through?"
He said, "Men will suffer, fight,
Even die for what is right,
Even though they know they're only passing through."

Franklin Roosevelt told me on the day before he died,
"One world must come out of World War Two,
Red and yellow, black and white,
We're all equal in God's sight,
We're all his children and we're only passing through.^^^

I can't find the book from which I got these words, and I don't remember who wrote it. I learned the melody from a fellow striking teacher back in '75--he had put strike-specific words to it.

It's getting very late: maybe someone else knows the song and can post the midi. If not, I'll post the chords for the verse and chorus tomorrow or the next day. The melody of the verse is very like "Jesse James"; the chorus ends the same but starts out a bit different.
