During a packed London concert, the lead singer of a world-famous punk band stunned fans by announcing he plans to give up his U.S. citizenship in protest of the Supreme Court’s decision to overturn Roe v. Wade. He told the audience he’s “not kidding” and promised they’d be seeing much more of him in Europe.

The next night, he continued his criticism during another U.K. show, blasting the direction his home country has taken.

Elsewhere at Glastonbury, pop star Olivia Rodrigo joined in, calling out the conservative justices by name — turning the festival into one of the loudest cultural reactions to the historic court ruling.
