Frontman and guitarist Billie Joe Armstrong cited the extended play as the one on which Green Day began to find its sound.

"Slappy" was a nickname given to him by bassist Mike Dirnt's friend Jason Relva (the subject of Green Day's later song J.A.R.).

The EP includes one cover, "Knowledge", which was originally by influential California punk band Operation Ivy.

"Paper Lanterns" was a popular Green Day song and a live staple for many years and was brought back for the 2010 leg of the 21st Century Breakdown World Tour.

It was later re-recorded during the Dookie (1994) sessions, and was released as a B-Side on the "Basket Case" CD single in the United Kingdom.
