Background: Screeching Weasel is an American punk rock band originally from the Chicago suburb of Prospect Heights, Illinois. The band was formed in 1986 by Ben Weasel and John Jughead. Since their formation, Screeching Weasel have broken up and reformed numerous times with numerous line-up changes. Ben Weasel has been the only constant member, though Jughead was present in every incarnation of the band until 2009.
Context: After the break-up, Weasel and Jughead formed a new band called The Gore Gore Girls, and Ben briefly performed in the original incarnation of The Vindictives. In 1991, the members of Screeching Weasel reunited for what was intended as a one-off gig to pay off debts the band incurred from the recording of Boogadaboogadaboogada!. The line-up consisted of Ben, Jughead, Vapid, Vermin, and Ward. After the show, Vapid discussed the idea of reforming Screeching Weasel with Jughead. All of the band's members agreed to reform, with the exceptions of Brian Vermin and Douglas Ward. To replace Vermin, drummer Dan Panic (Dan Sullivan) was brought in. Before recording their third studio album, My Brain Hurts (1991) for Lookout! Records, Weasel decided that he wanted to focus on singing and would no longer be playing guitar in the band. Vapid switched instruments from bass to guitar, and former Gore Gore Girls bassist Dave Naked joined the band. The recording sessions for the album also produced the extended play Pervo Devo.  After recording My Brain Hurts, Dave Naked was fired from the band and Scott "Gub" Conway, Panic's former bandmate, was brought in as the band's bassist to tour. After the tour, Johnny Personality of The Vindictives became the band's bassist, as Gub was committed to another band. By late 1992, the band had recorded the follow-up to My Brain Hurts, Wiggle, which also marked their first collaboration with producer Mass Giorgini, who went on to produce the vast majority of the Screeching Weasel catalog, and also became the bassist of the band from 1998 to 2004. Personality then left the band to focus on The Vindictives. Instead of adding a new member, Weasel moved back to guitar, and Vapid moved back to bass.  The band was then asked to record a cover of an entire Ramones album, Ramones (1992), followed later that year by Anthem for a New Tomorrow. Shortly after the record's release, Weasel decided that he no longer wanted to perform live, and Vapid left after falling out with the rest of the band. Screeching Weasel enlisted the help of Green Day bassist Mike Dirnt to record what they intended to be their final studio album. After the release of How to Make Enemies and Irritate People (1994), the band broke up for the second time.
