I think classic is the song gargoyle was thinking of. I found it at http://www.metrolyrics.com/ole-slew-foot-lyrics-johnny-horton.html

OLE SLEW FOOT
(Howard Hausey & James Webb)

High on the mountain, tell me what you see;
Bear tracks, bear tracks, lookin' back at me.
Better get your rifle boy before it's too late,
Cause the bear's got a little pig and headed through the gate.

He's big around the middle and he's broad across the rump,
Runnin' ninety miles an hour, takin' thirty feet a jump;
Ain't never been caught he ain't never been treed,
And some folks say he looks a lot like me.

[ harmonica ]

I saved up my money and I bought me some bees,
And they started makin' honey way up in the trees.
Cut down the trees but my honey's all gone,
Old Slew Foot's done made himself at home.

He's big around the middle...

[ harmonica ]

Winter's comin' on and it's twenty below,
And the river's froze over, so where can he go?
We'll chase him up the gully, then we'll run him in the well,
And shoot him in the bottom just to listen to him yell.

He's big around the middle...

There's a nice YouTube recording of Jim & Jesse singing it here (click)
The song was also performed a few times by the Grateful Dead
