Check out Raju Lama singing, "Sayad Timro Bato Ma", he's 100% lipsynching that song. Check out the part where he points out his mike towards the crowd and his voice is still clearly heard in the background. Thats very funny. Same goes to Nima Rumba in couple of songs. But the ones performed with the band looks genuine. Not good to deceive the crowd. Reminded me of Milli Vanilli who got busted for lipsynching.
