Olivia Rodrigo joined by Lily Allen in the stunning Glastonbury Festival setting

OLIVIA Rodrigo was joined by special guest Lily Allen as she brought a jaw-dropping array of pop-punk anthems and heartbreaking ballads to Glastonbury Festival tonight.

The 19-year-old American singer-songwriter and actress performed in front of thousands of fans on The Other Stage.

She invited Allen, 37, on stage to perform her 2009 single “F*** You” in response to the U.S. Supreme Court’s overturning of a ruling that protects women’s right to abortion across the country for nearly 50 years.

Like Billie Eilish last night, Rodrigo expressed dismay at the United States Supreme Court’s decision to overturn the historic 1973 Roe v. Wade verdict.

She described performing with Allen as “the biggest dream come true”, but said, “I’m devastated and terrified, so many women and so many girls are going to die because of this.”

Allen’s entry for the penultimate song of Rodrigo’s hour-long set drew one of the loudest cheers and chants of the evening from the huge audience before the couple share a long embrace.

At the start of his set, Rodrigo emerged after his five-piece all-female band teased his entrance several times to build anticipation ahead of his single “Brutal” from last year’s UK number one album. Acid.

She then launched into a reinvented punk-pop version of “Jealousy Jealousy”, a tongue-in-cheek song about the effect of social media on how young people see themselves.

Addressing the audience for the first time, Rodrigo said: “I’ve never seen so many people in my life, I’m so nervous! My name is Olivia and we are going to have a great time.

The standout performance from Rodrigo’s solo set was the heartbreaking piano ballad “Drivers License”, described by the singer as “the song that changed my life forever”.

She played the elegant black grand piano in center stage, smiling as the vast crowd sang the last verses to her in the early evening sunshine at Worthy Farm.

“Thank you Glastonbury, it was very special,” she told her audience.

When not seated at her piano, Rodrigo walked, ran and danced around her stage while delighting fans with tunes of Acida cover of Avril Lavigne’s ‘Complicated’ and a rendition of ‘All I Want’, the first song she ever released on a TV show High School Musical: The Musical: The Series.

She was presented with a purple guitar for “Hope Ur OK,” a hopeful song wishing the best to people in her past who suffered because of their identity (“My college friend grew up alone, she raised her brothers alone, her parents hated who she loved”).

The live version of the song, which features some of Rodigo’s best lyricism, evolved to include more drums throughout its opening verses, though its bridge remained as beautifully minimalist as ever.

This was followed by three songs that Rodrigo “wrote alone in my room about the boyfriend I didn’t feel good enough for”: “Enough For You”, “1 Step Forward, 3 Steps Back” and “Happier “.

She added: “Now I can play them for the biggest crowd I’ve ever seen at Glastonbury, so that’s pretty cool.”

Before Allen’s appearance, festival-goers were treated to “Favorite Crime,” a song written with producer Dan Nigro from a poem she wrote, and “Traitor,” which laments the betrayal of a former beau.

Once the ‘Smile’ and ‘The Fear’ hitmaker left the stage, Rodrigo ended his memorable set in euphoric fashion with ‘Deja Vu’ and ‘Good 4 U’.

While Rodrigo and Eilish will be remembered for demonstrating their prodigious talents at Worthy Farm, they should go down in Glastonbury history for adding their names to the list of people who used their platforms to express their beliefs.
