Originally captured as part of a series of four-track recordings Cobain made in 1988 while living in Olympia, Washington, the demo will appear on the companion soundtrack to Brett Morgen's documentary "Kurt Cobain: Montage Of Heck", with both due November 13.

Cobain and Nirvana recorded several versions of "Sappy" before it surfaced as a hidden track on the 1993 AIDS-benefit compilation album "No Alternative" under the title "Verse Chorus Verse."

A 1993 recording later appeared on Nirvana's 2004 box set, "With The Lights Out", and the 20th anniversary editions of "Nevermind" in 2011 and "In Utero" in 2013.
