Olivia Rodrigo performs "Buddy Holly" and "Say It Ain’t So" with Weezer at Lollapalooza

After performing songs such as, "vampire", "driver's license", "traitor", and "bad idea right?", Olivia Rodrigo asked the crowd if the show was anyone’s first concert. "You always remember your first concert. Very, very special moment. I remember my first concert. It was a very memorable night," she said, before introducing Weezer. "I watched this incredible band and I am so over the moon because that incredible band is actually here tonight to play a few songs. Will you please say hello to Weezer?"
