That's one of John Hartford's songs on the Album "Looks At Life."

I posted a partial tab on www.countrytabs.com taken from a 40sec sound clip...to wit:

There may be more verses....v.g.

Corn Cob Blues
D
Well the cowboy promoted the wedding you know
             G                         D
Between the songs of his rock and roll show

The groom was thin, and the bride was a tease
                G                      D
Recorded to the sound of his latest release
                G                   D
They both were members of the back up crew
                                    A       D
And the thin man was thinkin' those corncob blues

D
Well the rain came down and the crowd was slow
               G                      D
The cowboy hollered as he stubbed his toe
                                       
The signs on the trees from here to town
                G                   D
Hurricane Apple couldn't knock them down
                G                     D
The thin man stands in his water-logged shoes
                               A       B
And keeps on thinking of those corncob blues

Well......

Maybe Harpgirl...has more on the lyrics.
