"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. "Why Do You Want Him?" was the first song Armstrong wrote, back when he was fourteen. The title "409 in Your Coffeemaker" is taken from a prank Armstrong pulled on his teacher. The prank was that he put some Clorox cleaner in his teacher’s coffeemaker, and it was known as Formula 409, hence the name of the song. 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. "Knowledge" was originally performed by
Operation Ivy for their 1989 album
Energy. Green Day still performs the song live, often inviting fans onstage to play the band members' instruments for them during the performance of the song. All four tracks from
Slappy were included on the compilation album
1,039/Smoothed Out Slappy Hours in 1991.
Slappy remained in print until August 2005, when Green Day removed its catalog from Lookout! Records. Since March 24, 2009,
Slappy (along with
1,000 Hours) has been back in print as a bonus to the vinyl reissue of the
39/Smooth (1990) album. However, a possible error may have been made as
Slappy artwork is now tinted pink instead of dark red. ==Track listing==
