Maybe a nitpick, but I disagree with the rendition of "I'm a-gonna tell you, pretty Polly Ann", which sounds to me like

I'm going to tell you *a* pretty Polly Ann

Thing is, I have no friggin' idea what a "Polly Ann" would be, but it would seem to fit right in to the somewhat Zen-like aspect of Uncle Dave's lyrics here.

Also, on the recording I have (the canonical one?), he definitely sings

"Do love liquor and will take a dram".

although "will" could just as well be "we'll".

Anyhow.
