The group was founded after Fun responded to a newspaper advertisement placed by Weäsell and producer-engineer-performer Chris Graf, who were attempting to find a keyboard and saxophone player for a planned live band.
For the first several years of their existence, however, the founding trio remained home-bound, writing and recording tracks that would later appear on the discs Meat the Weasels Volume I: Fondue Cabaret and GenerationXcrement.
In 1992, The Weasels submitted a tape to the local alternative newsweekly's annual unsigned artists' showcase concert, and were selected as one of four finalists, despite the fact that no live version of the band existed.
Fun, Graf and Weäsell quickly assembled and rehearsed a stage presentation of their material, and won generally positive audience and critical reviews for their performance, despite losing the contest to a defunct industrial metal band.
Following Meat the Weasels' release, the group continued to perform live, though with continued instability in the drummer's seat, which was occupied for various dates by Petrocelli, Jordan Cohen (later of Powerman 5000 and Blue Man Group), Dave King, Doug Klein, Dan Roberts, Steve Scoons, Dave Berger and Steve Candlen; the latter two emerged as drummers of choice for The Weasels' middle recording period.
After the release of Leon’s Mystical Head, the band's core members decided that all subsequent albums would be recorded and engineered under their own direct supervision, with Graf taking a prominent creative role in the increasingly elaborate productions of Fun and Weäsell's compositions.
Fun and Weäsell were joined onstage by Jon Cohen (bass), drummer Scott Appicelli and hired hands Steve Watson (keyboards) and Nathaniel Ward (guitar).
GenerationXcrement featured performers from throughout the band's history, including the following musicians not credited elsewhere in their recorded canon: Mike Sheehan (keyboards), Andy Manion (guitar) and Mary Panza (voice).
Fun, Weäsell and D'Aloia return from the AARP Go The Weasels band, with session professional and instructional writer Art Bernstein replacing Al Kash on drums.
The album featured 15 songs: In 2021, Weäsell, Graf, early-era Weasels' drummer Dave Berger, and long-time bass collaborator Jon Cohen (with support from guitarists Chuck D'Aloia, Crick Diefendorf and Andy Baker, keyboardists Robert Lindquist and Dan McShaw, and sax players Daniel Ian Smith and Jeff Nania) issued a Weasels-adjacent album entitled High Fidelity Virtue Signaling Party, and credited to The Flying Bobs.
