"Thumb Hang" was recorded for this album but was was originally written by Lips and Robb Reiner in the 1970s when they were in high school. It was instead released as a bonus track on the USA, Australian, Japanese, German and Argentinian CDs of the album THIS IS THIRTEEN.
During the "Thumb Hang" recording session they also recorded new versions of "Metal On Metal", "666", "March Of The Crabs", "Forged In Fire", "Winged Assassins" and "School Love". It is likely they would have used these versions instead of the originals. They might not have used "March Of The Crabs" as they still used the original on MONUMENT OF METAL.
"March of the Crabs" is an instrumental.
