When we first heard that Girls’ Generation were scheduled to appear on both Live! with Kelly (that should be happening any moment now actually, set your DVR accordingly!) and Letterman, we were immediately anxious to know how Dave himself would greet them after their set. What we didn’t know was that Regis and Bill Murray would be the show’s other guests, or that they’d be decked out in Super Bowl-inspired attire while bearing witness to SNSD’s first foray into American television. As far as cultural exchanges go, it was a perfect storm: three extraordinarily cantankerous old dudes sharing a stage with the South Korean ninesome as they performed “The Boys,” the fiery lead single from their American full-length debut of the same name. It’s like a dream.
