What happened there? Did the sound guy mute Don's vocal track after a couple of words when he noticed Don's not even near the mic?
EDIT:
I see he's been using the same track for years at least for LITFL. Listen to all these performances phrase by phrase from "She said listen baby..." to the chorus. It's so obvious.

Not sure I'd even mind him lip-syncing if people knew it. But it's always been irritating to see comments like "His singing sounds great. Don Henley isn't what he used to be blablabla."
