haha thats funny... you know lip syncing is actually really common... Just the bands I toured with most of all them tracked vocals and guitars... I know alot of industry people involved with bigger named acts... and they all sing under a tracked vocal... in fact I know a front of house guy for this big christian band and he flat out told me that he could pull a show off with everyone missing except the drummer... all the bass, guitars and vocals were tracked... and if they're sick one night..he can pull the show off easily.. I could go on and on with stories
but ya that video is pretty fail
