Last night, the Swet Shop Boy and movie star Riz Ahmed was a guest on the first Tonight Show since the deadly white-supremacist riots in Charlottesville. And while he was on the show, Ahmed performed an a cappella version of “Sour Times,” a song he wrote a decade ago about the demonization of Muslims in the UK. Making a few subtle lyrical tweaks, he delivered it — on a bare stage, with just a microphone — as a response to those who might think about their fellow citizens as the other. Watch it below.

This is entirely beside the point, but I think Ahmed’s mustache looks cool.
