Thanks to two friends from Hobo Pie, Bob Woodcock and Barb Johnson, I have a Xerox of the sheet music! In addition to the chorus printed above it has two verses (to a different tune-- sorry)

Railroad train, railroad train, hurry some more
Put a little steam on just like never before,
Hustle on, bustle on, I've got the blues
Yearning for my Swanee shore
Brother if you only knew
You'd want to hurry up to---
Down yonder. . .

Summer night, Fields of white, Bright cotton moon
My but I feel glad I'm gonna see you all soon
Lasses cakes, Mammy bakes, I taste them now
I can hear the (politically incorrect term) croon
I'll see my sweetie once more
There's lots of kissing in store
