Overview

• Billie Joe Armstrong joined Dua Lipa on Oct. 12 at San Francisco’s Chase Center to perform Green Day’s 2004 ballad “Wake Me When September Ends.”
• Armstrong appeared midway through the set to loud cheers as Lipa introduced the performance as the night’s local-artist surprise.
• At the same venue the night before, Lipa covered “Piece of My Heart” in a nod to Janis Joplin and Big Brother & the Holding Company.
• The tour’s rotating tributes have recently included guest turns such as Gwen Stefani at Los Angeles’ Kia Forum, with additional cameos in New York.
• Two Seattle dates close the North American run before shows in Mexico City and across South America, and Lipa told Rolling Stone she is working with Mark Ronson on new music.
