And then there's the video on YouTube where the vocal in the final verse of Take It Easy starts a bit early, so he has to sing the rest of the song live - and sounds fine to me.

On the other hand, Austin just posted a Long Run clip in another thread where the vocal sounds live to me. One note very much out of tunein the first verse. He's reading the lyrics, but that doesn't mean he's singing live - he still would have to "mime" the correct words if he was lip syncing.

Whenever I say that Don is lip syncing, it's not a fact, just an opinion. Maybe he's singing live AND there's a track as well. That would explain the "'cause" we hear that he doesn't sing.
