Following the album's release, the band was threatened with a lawsuit from the real International Red Cross; as a result, the group became Redd Kross, and returned in 1984 with Teen Babes from Monsanto, a collection of covers of artists ranging from David Bowie to the Rolling Stones and the Shangri-Las. That year, they also appeared in and composed the music for the no-budget film Desperate Teenage Lovedolls, which included their transcendent cover of the Brady Bunch's "(It's A) Sunshine Day." Complete with new guitarist Robert Hecker and drummer Roy McDonald (no relation), 1987's Neurotica, with songs like "Frosted Flake," "The Ballad of Tatum O'Tot and the Fried Vegetables," and "Janus, Jeanie and George Harrison," appeared primed to push Redd Kross out of the underground, but their label, Big Time, folded shortly after the album's release, and legal hassles prevented the band from recording any new material under its own name for three years.

Instead, as the Tater Totz, the McDonald brothers corralled Three O'Clock member Michael Quercio and former Partridge Family kid Danny Bonaduce for 1989's Alien Sleestacks from Brazil, the title a nod to the Sid and Marty Krofft children's series Land of the Lost. A collection of satiric and surreal covers, the LP included renditions of "Give Peace a Chance," "We Will Rock You," and Yoko Ono's "Don't Worry Kyoko." Prior to another Tater Totz effort, 1989's Sgt. Shonen's Exploding Plastic Eastman Band Mono! Stereo (recorded with ex-Runaway Cherie Currie and future Foo Fighter Pat Smear), the McDonalds detoured into another side project, Anarchy 6, for the 1988 mock punk tribute Hardcore Lives! Finally, in 1990 Redd Kross landed a deal with Atlantic, issuing the surprisingly straightforward Third Eye. After an appearance (alongside David Cassidy) in the kitschy 1991 film Spirit of 76, the band issued a handful of singles before 1993's Phaseshifter, augmented by guitarist Eddie Kurdziel, keyboardist Gere Fennelly, and drummer Brian Reitzell. Minus Fennelly, Redd Kross returned in 1997 with Show World.

The band went on hiatus with an uncertain future following Kurdziel's drug overdose death (at age 38) in 1999. However, in 2006 the McDonald brothers reunited with late-'80s bandmembers guitarist Robert Hecker and drummer Roy McDonald and began making live appearances once again, including individual shows, festival dates, and tours that saw Redd Kross perform across the United States and in Canada, England, and Spain. A January 2007 show in Madrid was documented on the Got Live If You Must! DVD, released the following year by Bittersweet Records. In 2012 the band released Researching The Blues with longstanding indie giant Merge Records. Their seventh studio album was also their first collection of new songs in 15 years.
