Well, this nine pound hammer is a little too heavy
For my size, honey for my size
I'm goin' on the mountain, gonna see my baby
And I ain't comin' back, Lord I ain't comin' back

Oh, roll on buddy, don't you roll so slow
How can I go when my wheels won't roll
Roll on buddy, pull a load o'coal
How can I go when my wheels won't roll
[ Lyrics from: http://www.lyricsfreak.com/j/johnny+cash/nine+pound+hammer_20281387.html ]
Well, it's a long way to Harlem, it's a long way to Hazard
Just to get a little brew, just to get a little brew
Now when I'm long gone you can make my tombstone
Out of number nine coal, out of number nine coal

Roll on buddy, don't you roll so slow
How can I go when my wheels won't roll
Oh, roll on buddy, pull a load o'coal
How can I go when my wheels won't roll
