During their last concert U2 in Las Vegas on Saturday, the singer Bono expressed his support for Navalny’s widow, dedicating it to her “Don’t dream it’s over“.

Bono asked the audience to help him with the song in her honor Yulia Navalnaya.

The singer encouraged the audience to sing along with him to record a cover of the song and “send it to anyone who loves freedom”.

As the crowd sang along, Bono—a well-known human rights activist—rhythmically called out her name: “Julia, Julia.”

Bono also dedicated from the stage “All I Want is You» to the First Lady, Jill Biden, who was attending the concert.

“I dedicate this to all the great women in our lives and all the great women in parts of the world who are going through very difficult circumstances,” Bono, 63, said. “One woman in particular who is with us tonight is a teacher. She’s your first lady — so that’s for Jill Biden,” he said to applause.
