Fresh off releasing her brand new song, Florence Welch of Florence and the Machine joined Arcade Fire on stage in London to perform “Dog Days Are Over”.

Welch has been a longtime fan of the band saying, “I love Arcade Fire so much, ever since Funeral. I’d love to collaborate with them. I met Win [Butler] and I was so starstruck, I cried. It was so embarrassing…”.

Boy George also performed with the band, joining them for “Karma Chameleon”.

Earlier this week, Florence and the Machine released their first new song since 2016, “Sky Full of Song”. It is being released as a 7″ single for Record Store Day 2018.
