“I felt so sorry for her!”

Cyndi Lauper’s performance at Glastonbury on Saturday was heavily criticized after massive sound problems occurred.

Festival-goers had trouble understanding the vocals of the Girls Just Wanna Have Fun singer as her voice was drowned out by booming bass.

After a few songs, 71-year-old Cyndi sang “Rocking Chair,” and she seemed to struggle with her pitch and timing.

The sound problems seemed to be resolved when she got to her hit “I Drove All Night.”

However, during her 1984 song “Time After Time,” Cyndi stumbled again as she fell behind the band, suggesting she was having problems with her in-ear monitors.

The singer was seen looking at the members of the production team at the side of the Pyramid stage as she continued to perform her show for the audience.

The crowd came to Cyndi’s aid, lifting her up and singing along to her mega hits “True Colors” and “Girls Just Wanna Have Fun.”

Despite the problems, Cyndi, who has over 40 years of stage experience under her belt, was a professional through and through.

Some fans complained on X (formerly known as Twitter) about the “terrible sound issues” during the Legends set.

“Terrible sound problems with Cyndi Lauper. I really felt for her.”

“So sorry for #CyndiLauper – you could tell she was upset about the sound issues.”

“@CyndiLauper was really disappointed with the sound system at @Glastonbury. You couldn’t hear her singing but you could see how much effort she was putting in to rouse a crowd that couldn’t handle the poor sound. Everyone around us was so disappointed.”

“Some obvious sound issues, but I still enjoy it.”

“There are some serious sound and timing issues on the Cyndi Lauper set. What a shame.”

Other fans praised Cyndi’s performance, calling it “magical” and “fabulous.”

“I’m looking at Cyndi Lauper right now and she still has the magic.”

“Oh my God, Cyndi Lauper is still so fabulous.”

“Cyndi Lauper, what a queen.”

“What a set!!!”

MailOnline has contacted Glastonbury for comment.

Cyndi looked incredible at the matinee performance wearing a silver corset with matching pants and a long blue ruffled coat.

She turned to the audience, which stretched to the back of the Pyramid Stage, and asked, “How are you? I see you. I love you. You are everywhere.”

She opened her set with the 1980s song “The Goonies ‘R’ Good Enough” before later pulling out a recorder and playing the 2008 single “The Nightlife.”

But the American singer also used her time on stage to passionately advocate for women’s rights.

She said: “It is time for world leaders to understand that women make up half the world’s population 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.”
