The band appeared at Gallagher Square outside Petco Park to promote its upcoming coming-of-age film, Nimrods. Developed by Kirk alongside Green Day, Nimrods follows three friends who travel from Kansas City to Los Angeles after mistakenly believing their band has been selected to open for Green Day on New Year’s Eve. The soundtrack will also include the new Green Day song “I’m Never Gonna R.I.P.” Green Day last released its studio album, Saviors, in January 2024. Earlier this year, mxdwn reported on producer Linda Perry’s criticism of Green Day and Billie Joe Armstrong over her removed involvement with 21st Century Breakdown.
