Several countries have threatened to withdraw from next year's Eurovision Song Contest if Israel, which has participated since 1973, is allowed to take part.
Ireland, Slovenia, the Netherlands, Iceland and, most recently, Spain, have all said they will not participate if Israel is allowed to.
It follows protests against 2025 Israeli entrant Yuval Raphael and 2024 performer Eden Golan, who said she received death threats.
Bambie Thug, who placed sixth for Ireland with song Doomsday Blue at 2024's contest, says she's proud of her country for taking a stand.
"I 100% feel the UK should follow suit, I don't know what artist would want to represent the UK this year," she says.
Criticism of Together for Palestine has tended to suggest that celebrities and singers shouldn't get involved with politics or complex causes.
But singer Cat Burns tells Newsbeat that events like this are valuable, and believes they can raise further awareness.
"I think it can spark a lot of change," she says.
"If people see their favourite artist here maybe that will spark people to do some research and support as well.
"I think it's massively important"
But, Cat adds, speaking out is a personal choice.
"I think every artist is their own person and they're going to choose what is right and comfortable for them."
