Promoting her new live record/DVD, Live in London, Regina Spektor stopped by Late Night with Jimmy Fallon last night to play “Dance Anthem of the ’80s” from her last studio LP, Far, with The Roots as her backing band. It’s a fun, relatively faithful rendition, but the best part might be when ?uestlove shouts in the microphone for the band to “solo!” (à la Ryan Adams’ “Halloweenhead”). Enjoy the video above, as well as clips from her new DVD here, here, and here.
