"Silkworms" is an unreleased song written during the Chinese Democracy sessions. It is written by Chris Pitman and Dizzy Reed. Currently, the only rendition of "Silkworms" we've heard are the live versions from 2001.
The song was first preformed live on January 1st, 2001 at the Las Vegas House of Blues as part of the band's New Year's Eve show. It was the first song of the encore.
Silkworms recently leaked to the general public in full, along with a reworked Oh My God.
