Ryan Lewis and Macklemore apparently hopped up on a bus in New York, then regaled passengers with a surprise performance of "Can't Hold Us," in a CBS effort to announce that they will be performing during the Grammy Awards on Jan 26. But this is the Internet, and this is a potentially viral video, so critics are out in full force on YouTube, where the video is housed, asking pretty spot-on questions about whether this was staged or not. Did nobody notice the cameras? And how is the front of the bus entirely empty?
