Singer Olivia Dean dedicated her song Carmen to her grandmother and other members of the Windrush generation as she neared the end of her set on the Pyramid Stage at Glastonbury.

The neo soul singer, 25, who was named the winner of the BBC Introducing artist of the year award last year and whose album Messy earned her a Mercury Prize nomination, followed rock band Squeeze, who opened Friday’s Pyramid Stage performances.

Wearing a T-shirt with her grandmother’s face on it, Dean said: “She came to this country when she was 18, never been on a plane… she had my mum quite young, my mum had me and I’m a product of her bravery.

“So this song is for my granny, to the Windrush generation, for any immigrant, anyone’s who’s brave enough to move.”

Dean wiped away tears and commented on “what a beautiful day” it was before she played her last song of the set, Dive.

Later, 28-year-old British-Albanian singer Dua Lipa will headline the festival and is expected to play hit songs including Houdini and Training Season from her third studio album, Radical Optimism.

Glastonbury organiser Emily Eavis told BBC Radio 2’s The Zoe Ball Breakfast Show there will be “no big surprises” at this year’s event, but she did say Coldplay’s Saturday headline slot will be a “huge moment”.

American R&B singer SZA will headline on Sunday, while country star Shania Twain will play the coveted Legends slot.

Earlier, Eavis defended the festival line-up amid criticism that there is a lack of rock bands, telling the PA news agency: “I think the line-up reflects what’s happening in the music world at the moment – there aren’t a lot of new rock acts to choose from, if I’m honest.

“Hopefully that will emerge again, my heyday was 1995 with Pulp and Oasis and Radiohead… and that was great, but music changes all the time and right now this is where we’re at.

“Every year, we’ve been criticised for being too rock, too grime, too hip hop, too pop… it’s just part of our year.

“Generally it’s not from the public… everybody’s really happy and excited to be here.”

This year’s festival is taking place in the week before the General Election, and Eavis said: “I feel a bit like we’ve stepped out of the election, even though it’s next week.

“We were working on having voter registration booths, but then the day moved.

“It’s a big one for us, we’ve never had a pre-election festival.”

Glastonbury organisers have also decided the Euro 2024 football tournament will not be broadcast at the festival – with England set to face Slovakia in the last 16 at 5pm on Sunday.

Eavis said the festival set up a screen to watch fixtures during the World Cup in 1998, but times have changed.

“We used to have a screen here as no-one had any means of finding out what even the result was because we were so cut off from the outside,” she said.

“Now everyone’s connected, and I think, you know, it’s a music festival.

“I’m sure if people want to see it enough they can check for results or whatever on their phones.

“But hopefully I’m encouraging people to put their phones away and forget about the outside world.”

Music fans at Glastonbury enjoying Friday’s line-up could be met with the “occasional light shower” but the day will mainly be “dry and bright”, according to the Met Office.

Temperatures are expected to reach high teens to low 20Cs over the weekend.

Thursday’s festivities included a tribute to the late DJ Annie Nightingale, the first female presenter on BBC Radio 1 who died in January at the age of 83.

Festival founder Sir Michael Eavis was among Thursday’s performers and was met with rapturous cheers by a crowd of thousands as he appeared in a wheelchair on the Park stage.
