Three previously unreleased Green Day songs have been posted online. Called "Jennifer," "Stay" and "Maybe Forever," the newly unearthed tunes date back to the late 1980s and were recorded at a show on July 22nd, 1989 in Berkeley, California when the punk trio opened for Killdozer.

These are the only known live performances of the songs and were performed before the band had released its debut album, 1990's 39/Smooth. None of the songs have ever surfaced as a studio recording. All three feature original drummer John Kiffmeyer.

"Jennifer" was often referred to as "Future Old Boy," while "Stay" was thought for years by fans to be called "World Vs. World." Green Day frontman Billie Joe Armstrong wrote the latter song for a film.

Armstrong hinted to fans on Instagram in December that he was writing new Green Day songs but did not share any more details. The band kept a low profile for much of 2018, although they posted photos over the summer indicating that they had been rehearsing classic early albums like Dookie, Insomniac and Kerplunk! in full.
