Cyndi Lauper’s performance at Glastonbury was plagued by sound problems

The set was reminiscent of Diana Ross’ performance in the Legends slot two years ago, when fans complained about wrong notes and shaky vocals.

As with that show, the audience came to Lauper’s aid and sang along to hits like “True Colors” and “Girls Just Wanna Have Fun.”

And with more than 40 years of stage experience under her belt, Lauper carried the show with the sheer force of her personality.

She entered the stage in a stunning silver outfit, combined with a powder blue coat and matching hairstyle.

“How are you?” she asked the audience, which stretched to the back of the Pyramid Stage. “I see you. I love you. You’re everywhere.”

She started off with the soundtrack classic “The Goonies – ‘R’ Good Enough” from the 1980s, before moving on to the censorship-critical “She Bop” – a piece about the joys of masturbation.

She even played a recorder solo during the 2008 song “Into The Nightlife”.

But the 71-year-old also used her stage presence to passionately advocate for women’s rights.

“It is time for world leaders to understand that women make up half the world’s population,” she said, “and that we deserve to be treated equally.”

At the end of the performance, she thanked the audience and said: “Have a great party, kids.”

But her expression revealed that it had been a demanding show.

In a subsequent interview with BBC Breakfast, she admitted that there had been “technical difficulties” that had to be overcome.

“Sometimes you stand up there and think, ‘What?'” she said in an interview that will air Sunday morning.

“But it doesn’t matter because the spirit is there… The spirit of these people. It was great. I had fun.”

Joining Lauper on Saturday’s lineup are artists such as Jessie Ware, Disclosure, Little Simz, Keane, The Streets and Gossip.

Before her set, the Pyramid Stage was opened with a rousing performance by Femi Kuti, who got the lunchtime crowd dancing to the jazzy, soulful grooves of songs like “Pà Pá Pà” and “Corruption Na Stealing.”

He also brought his son Fela, who amazed his fans by holding a single note on the saxophone for almost two minutes.

Next up was Nigerian singer Ayra Starr, who made history as the first Afrobeats artist to perform on the Pyramid Stage.

She did it naturally, delivering powerful vocals and seductive dance moves on sun-kissed songs like “Rush,” “Woman Commando,” and “Bloody Samartian.”

The current hit “Commas” was so well received that she sang it twice before finishing with the uplifting sing-along song “Sability”.

“Next time I come here, I’ll be the headliner, okay?” she said as she left the stage.

The first act to enter the Other Stage was the folk duo The Staves, who got the festival-goers in the mood for Saturday with a bucolic set of folk-rock harmonies.

Sisters Camilla and Jessica Staveley Taylor performed songs from their twelve-year career, from the gentle acoustic melodies of “In The Long Run” to the more strident feminist anthems “Good Woman” and “All Now.”

Meanwhile, BBC News presenter Ros Atkins made his Glastonbury debut with a heavily backed set of drum and bass bangers at the Stonebridge Bar.

Coldplay will headline the Pyramid Stage for the fifth time on Saturday night, setting a record.

Rumour has it that frontman Chris Martin was at Worthy Farm that morning to hand out LED wristbands for their show and urge fans to vote in next week’s general election.
