Banjer, with the exception of the bridge, which "Bill Groggins' Goat" doesn't have, the tunes are almost identical. (and another "Speckled Bird" clone is "I'm Thinking Tonight of My Blue Eyes," and a while back I posted another, "You're a Detour on the Highway to Heaven."

Here's "Bill Groggins' Goat," which I can't find in the digitrad (which I've found many times doesn't mean it isn't there--songs hide from me when I go looking there).

Bill Groggins' goat
Was feelin' fine,
Ate three red shirts
Right off the line.

Bill took an axe,
Gave him a whack,
And tied him to
The railroad track.

The whistle blew,
The train drew nigh;
Bill Groggins' goat
Was doomed to die.

He gave a grunt
Of awful pain,
Coughed up the shirts,
And flagged the train.
