Lyrics:

As I listen for the whistle, lie awake and wait
Wish the freight train didn't run so near
'Cause the rattle and clatter of that old fast freight
Keeps makin' music in my ear
Go bum again, go bum again
Clickety clack, clickety clack
The wheels are saying to the railroad track
Well, if you go, you can't come back
Hear the whistle blow, hear the whistle blow
If you go, you can't come back
If you go, you can't come back
Well, I wouldn't give a nickel for the bum I used to be
Work as hard as any man in town
I got a pretty gal, she thinks the world of me
Man would be a fool to let her down
Go bum again, go bum again
Clickety clack, clickety clack
The wheels are saying to the railroad track
Hear some whistle blowin', hear some whistle blowin'
Clickety clack, clickety clack
Go bum again
So ev'ry night I listen, wonder if it's late
In my dreams I'm ridin' on that train
I feel my pulse a-beatin' with that old fast freight
And thank the Lord I'm just a bum again
Go bum again, go bum again
Clickety clack, clickety clack
The wheels are saying to the railroad track
If you go, if you go, you can't come back
