Kiwi, at the Library Club 1981. The song is a full-on, over the top cover of "I am The Walrus" by two (three?) musicians, an excerpt from a sociomusical relic, a cassette recording called Kiwi's Last Stand. Lead singer Tommy Elskes is still playing in Texas (*update, no, the google is telling me something about Colorado and now New Orleans...) He's put out a couple of albums and there are videos on Youtube to be found. I think that Kiwi was from Texas and moved up to Fayetteville, or played in Fayetteville alot in the 1970s. Beyond that I don't know much and would be grateful to hear more in comments.
* note this recording is also thanks to Orlis! Download link at here.
