Found it, it's called Lightnin' Hopkins In New York, and is presumably the same LP to which everyone refers above. Mine is issued on Barnaby/Candid as Z-30247 (AL-30247) and the liner notes indicate that it is a re-issue on Barnaby of a Candid Records release from the early sixties--so I maybe that means it's not a concert recording from 1970. The notes quote a "down beat" magazine review of the original release, authored by a John S. Wilson, which might clarify the date. The cut Mighty Crazy is over 7 minutes long and definitely contains the dialogue about wine mentioned in clueless don's original post.
