Lady Gaga closed the FireAid concert in Los Angeles with a live performance of her hit "Shallow" and a brand new song written for the occasion.

Pink, who always dials it up to 100, performed Janis Joplin’s “Me and Bobby McGee” and Led Zeppelin’s “Babe I’m Gonna Leave You.” While introducing John Mayer, she addressed the crowd: “Ladies and gentlemen, and every other gender which absolutely exists,” seemingly a reference to President Trump’s “two gender” declaration.
