Greta Thunberg is increasingly using the medium of music – including punk, rock and garage – to help deliver her pro-Palestine messages to wider audiences.

The Swedish political activist appeared on stage at British rock star Sam Fender‘s recent gigs in Scandinavia, with the Newcastle musician inviting Thunberg, 22, and her fellow campaigners to speak out on stage in Copenhagen.

Geordie singer Fender, 31, has huge appeal, regularly selling out stadiums across the UK and Europe.

With his guitar strapped to his chest, the star stepped aside after a number and asked his audience to ‘give a warm welcome to Greta Thunberg’ as he announced the campaigner on stage in the Danish capital.

Draped in the black-and-white Palestinian keffiyeh scarf, the Swedish eco-activist led the crowd in impassioned chants of ‘Free Palestine‘.

Currently sporting a trendy blunt fringe, also known as punk bangs, Thunberg has also been pictured in recent days wearing the sold-out Bohemians x Fontaines D.C. football shirt.

The colourful shirt is the third team kit for Dublin football club, Bohemian FC, known as ‘Bohs’.

The jersey is designed by Fontaines D.C. guitarist Carlos O’Connell, with 30 per cent of proceeds going to Medical Aid for Palestinians.

The Bohs’ Chief Operating Officer is Daniel Lambert, who manages the controversial band Kneecap.

Band member Liam Og O hAnnaidh, who performs under the stage name Mo Chara, is accused of displaying a flag in support of the Hezbollah at a gig at the O2 Forum Kentish Town in November last year.

He was charged with a terrorism offence for displaying the flag ‘in such a way or in such a circumstance as to arouse reasonable suspicion that he is a supporter of a proscribed organisation’.

The case has been adjourned until 26 September.

As Thunberg led a flotilla bound for Gaza on Monday, she was supported by British rap punk duo Bob Vylan.

The band caused an uproar at Glastonbury when they chanted ‘death to the IDF [Israel Defence Forces]’ at Worthy Farm crowds.

The group’s frontman is 34-year-old poet Pascal Robinson-Foster and the Ipswich-raised grime-punk pair were previously rejected by record labels as ‘too extreme’ to sign.

Yet they enjoyed a primetime spot not only on Glastonbury’s West Holts Stage but also on the BBC – prompting furious protests.

Thunberg is currently leading a group of around 20 boats, containing 350 campaigners.

The flotilla had been earlier forced to turn back just hours after leaving Spain but is now on its way once more, with its aim being to break ‘Israel’s illegal siege on Gaza’ and open up a humanitarian route.

Ahead of her departure from Barcelona, Thunberg told reporters from her boat Madleen: ‘We are doing this because no matter what odds we are against, we have to keep trying, because the moment we stop trying is when we lose our humanity.’

She will travel from Barcelona alongside Game of Thrones actor Liam Cunningham and Ada Colau, the former mayor of Barcelona, amongst others.

Her first attempt to reach Gaza in June after setting off from Italy was thwarted by Israeli forces, who boarded the vessel in international waters and detained her.

Bob Vylan said the flotilla, which were flying Palestinian flags and was organised by Freedom Flotilla Coalition (FFC), was packed with ‘brave individuals’ who were ‘attempting to do what should have been done by government intervention a long time ago.’

She and 11 passengers were taken to Israel, and given the choice to be deported or arrested.

This week, US political commentator Meghan McCain launched a stinging attack on Greta Thunberg’s appearance by comparing her to a character from the movie Shrek.

McCain left a snarky remark comparing the 22-year-old activist to Lord Farquaad in response to a video Thunberg had made defending Palestine.

‘I refuse to take anyone talking about politics seriously with uneven bangs and this sh***y Lord Farquaad hair,’ 40-year-old McCain wrote. The post has since been deleted.

Her controversial comments about Thunberg’s appearance sparked a fierce backlash on X, with one critic questioning why she felt the need to resort to such a ‘mean girl comment.’

‘Surely, you must know what it feels like when someone criticizes your appearance. Do better!’ the critic wrote.

‘I refuse to take anyone talking about politics seriously when they have to use their last name to get them places,’ another added, referring to McCain’s late father, Arizona Senator John McCain.

‘A person’s appearance has zero to do with their integrity or passion about any cause. You should delete this. It’s beneath even you,’ a third chimed in.
