ARCADE'S EXTRA GAME: In case it was past your bedtime, here's Arcade Fire's Roman Coppola-directed TV special, Here Comes the Night Time, which followed the Saturday Night Live episode featuring the PoMo faves as musical guests. Night Time finds the band playing en costume in a Montreal salsa club, and their performances of songs from new album Reflektor (Merge) are punctuated by bizarro comedy spots featuring guests like Michael Cera, Bill Hader, James Franco, Zach Galifianakis, Aziz Ansari, Rainn Wilson and Bono. It's a trippy half-hour that's reminiscent, in spirit, of Magical Mystery Tour, SNL, Monty Python and the trailers that play in the middle of Grindhouse. Enjoy. On SNL, meanwhile, the band played the title track (and first single) from the new album, as well as "Afterlife," and participated in a game-show sketch called "New Cast Member or Arcade Fire?"
