Overview
- Green Day gave an unannounced pop‑up performance on a Mister Freezie’s ice cream truck in Gallagher Square to surprise Comic‑Con attendees on Friday, July 24.
- Frontman Billie Joe Armstrong sang “Basket Case” from the truck roof, tossed ice creams, T‑shirts and cassette tapes into the crowd, and the band later handed out frozen treats and merch from inside the truck.
- Actors Mason Thames and Jenna Fischer and writer‑director Lee Kirk watched the set in support of Nimrods, which the band used the stunt to promote.
- The Nimrods soundtrack, which includes 22 Green Day songs plus a new track called “I’m Never Gonna R.I.P.” and four unreleased live recordings, is due July 31 while the film opens in the U.K. on Aug. 11 and in U.S. cinemas on Aug. 14.
- Fan videos and press coverage quickly spread the clip online, underscoring the band’s use of guerrilla promotion to reach pop‑culture audiences and build buzz in the run up to the film’s release.
