I have recently started appreciating Jerry Garcia, now that he's no longer with us, and I am surprised at what a bluegrass fan he was and how well he played the banjo. I was never a Dead Head, but I do appreciate his talents. Here's one that he did on Old and In the Way that I really like:

PIG IN A PEN
(Traditional)

(CHORUS)
A......................................................................D
I got a pig at home in a pen, corn to feed him on.
A..................................................E7...........................A
All I need's a pretty little girl to feed him when I'm gone.

Going up on a mountain to sow a little cane.
Put that old gray bonnet on, little Liza Jane.

Going up on a mountain to sow a little cane.
Raise a barrel of sorghum, sweet little Liza Jane.

Dark clouds a-rising, sure sign of rain.
Get your old gray bonnet on, Little Liza Jane.

Yonder comes that gal of mine. How do you think I know?
Tell by that gingham gown hanging down so low.

Bake them biscuits, baby. Bake 'em good and brown.
When you get them biscuits baked, we're Alabama bound.
