Greta Thunberg, the 18-year-old climate activist, sang and danced onstage at a recent concert while a crowd cheered.

At the Climate Live 2021 event in Sweden Saturday, where Thunberg was a speaker, she got in front of the crowd with a microphone and sang along to Rick Astley's 1987 hit song "Never Gonna Give You Up." The moment was documented and shared in a TikTok by the official Climate Live 2021 account, and Astley tweeted it as well.
