as one of the most successful bands of the swing revival: after climbing to number one on Billboards Top Heatseekers, Zoot Suit Riot became the first album of the swing revival to crack the Top 40 on the Billboard 200, peaking at number 17 and spending an ultimate total of 53 weeks on the charts. In June 1998, the album had sold 500,000 copies in the United States, going on to surpass sales of 1.4 million by August. Suddenly finding themselves in hot demand, the Daddies immediately started touring again. Spending the majority of 1998 and 1999 on the road, the band were now playing close to 300 shows a year, carrying out both headlining and supporting tours of the United States while traveling internationally as one of the headliners on the 1998 Warped Tour beside Rancid, NOFX and Bad Religion. By this time, the group's touring conditions had greatly improved, thus enticing Dan Schmid – who had originally left the band due to health concerns – to return as the Daddies' bassist at Perry's request. Although the Daddies were experiencing commercial success under the guise of swing revivalists, having been declared the "leaders" of the movement by Rolling Stone, the band openly contested being labeled a retro act at the exclusion of their dominant ska and punk influences and modernist lyricism. While still vocal supporters of both the swing revival and its bands, the Daddies adamantly tried to disassociate themselves from the swing scene and in particular its nostalgia-based mentality: Perry explained to Spin in July 1998, "it's not our mission to be a swing band. I'm not a guy from the '40s. That's why we play ska and use heavy guitars", noting elsewhere "I can't fully take us out of the retro classification, but we harp on the fact that we're contemporary music". Thusly, the Daddies avoided touring with swing bands, selecting Latin rock group Ozomatli and ska/soul band The Pietasters as support on their first headlining U.S. tour, and opening for Argentine rock band Los Fabulosos Cadillacs on their 1998 North American tour. At one point, the Daddies attempted to arrange a tour with Primus which never materialized; said Perry, "I know there are people who come to our shows who'd like nothing more than for us to play swing 24/7 ... there are plenty of bands who want to be swing bands and swing bands only.
