Thanks for including me in the Lip Dub Stars channel. It's not easy to get people to see creative work, and you have helped me. Its my mouth singing, but I realize it's not a real lip dub, in the current way we think of lip dubs. I can't say thanks enough though.

No, it's not a bad usage :-)
That's Justin's mouth too... so... why not !

Honestly, the purpose of the mouth was to separate the actor from the singer. Since he is not the singer of the band, I didn't want people to get confused. More importantly, I didn't want to offend the singer of the band, since they aren't well known at this time. My original idea for the thing, was to have it look like he was actually singing in all those stop motion shots. Which would be a much better effect overall, but one I will have to save for the future. The piece of paper I have on his mouth right now is stamped with the band logo. And I tried to make it feel as if it's its own character. Thanks for the interest.
