British superstar DJ Fatboy Slim paid tribute to teenage climate activist Greta Thunberg by performing a remix of his hit song "Right Here, Right Now," using samples from her dramatic UN speech.

The 56-year-old artist played the mash-up, made by South African electronic artist David Scott, at a show in Gateshead, northeast England, last Friday, with a video clip of the performance recently going viral on social media.

The remix samples Thunberg's demands for action against climate change in her fiery speech at the United Nations last month to be taken "right here, right now," using it during each refrain of the song's title.

It also includes other excerpts from the 16-year-old Swede's speech. "When Greta spoke to the UN and I saw the video and it was quite late at night, and as soon as she said 'right here, right now,' the Fatboy Slim song popped into my head and I just knew in that moment I had to create a mash-up," Scott said.
