Nine Pound Hammer

See this nine pound hammer (nine pound hammer)
Is a little too heavy (little too heavy)
For my size (for my size)
For my size

Now roll on buddy (roll on buddy)
Don't you roll so slow (roll so slow)
How can I roll (how can I roll)
When the wheels won't go

I'm going on a mountain (going on a mountain)
To see my baby (to see my baby)
And I ain't coming back (ain't coming back)
No I ain't coming back

Now roll on buddy (roll on buddy)
Don't you roll so slow (roll so slow)
How can I roll (how can I roll)
When the wheels won't go

Ain't one hammer (ain't one hammer)
In this tunnel (in this tunnel)
That rings like mine (rings like mine)
That rings like mine

Now roll on buddy (roll on buddy)
Don't you roll so slow, roll so slow)
How can I roll, how can I roll)
When the wheels won't go

Now roll on buddy (roll on buddy)
Don't you roll so slow (roll so slow)
How can I roll (how can I roll)
When the wheels won't go
