Lip synched I guess a better word for it. I had advance knowledge of this project thanks to our favorite hipster, blogster www.extrawack.com. (Devo 2.0) I didn't know that they were appearing at the local elementary school until my son showed up with these Devo 2.0 stickers. When asked about the show, son responded: "The only way I'd pay for that was if I was blind and deaf." Now, that's an endorsement.
