Do Vitas lip-sync

I think so.. Though his dynamic 'dance', his voice is so natural and stable.. effortless...

Adding to above answer:

Vitas does NOT lip sync in live concert. I have seen him three times from the front row! He sings live. All performers sync on TV. Vitas is very good at dancing and singing at the same time, but it is very evident his concerts are live! You can even hear his live voice when he pulls the mic away. Why will people just not believe that he is THAT GOOD!!!???
