Well....Which lines? I don't see it.
Starting with "Baby that preacher gave you in the spring" ... "with a Bible around his neck".... Etc
Lines going all the way back to the meta-physical poets...
Whoops... Hang on...
.. It all hinges on that line "without a little Barleycorn"
Where the trials and travesty of making alcohols are reflected in the effects of it... Again, read some meta-physical poetry!.
