Two nights ago in London, Arcade Fire frontman Win Butler grandly affirmed his dedication to doing goofy shit. The band was performing that night at the Roundhouse, and before the show, as people in formal wear were filing in, Butler, in a skull mask and hoodie, sang his band’s “Reflektor,” without amplification, as a mariachi band played behind him. He looked sheepish, if you can look sheepish while wearing a mask. Watch video below.

Was that an e-cigarette?

UPDATE: Arcade Fire have shared another angle…
