In 1982, a representative from Corwood industries (a/k/a Sterling Smith, a/k/a/ Jandek) released his fourth album, Chair Beside a Window. The album included a track entitled “Nancy Sings” which featured a new vocalist, known only as “Nancy.” From the above link:
Nancy was … a southern Ohio cosmopolitan hillbilly type who ran across my path one day and I asked her to sing what I had written as I played the guitar. There were no notes or anything and she just picked up the paper with words and sang and I played guitar as simple as that!
-Sterling Smith in a personal letter to Irwin Chusid, December 1982.
