The "official video" in the Fleetwood Mac youtube channel has the same sound as the Dreams version included in the 1980 Fleetwood Mac Live album. Don't know if this was already asked: Is that video the actual performance of the song included in the album? Or they put the audio in that video, but it's another performance? If so, the lip sync work is very good.
