I received a copy myself yesterday. Yes, it uses real audio with Mick's live vocals, but the picture doesn't seem to be restored.
The "Best of Frost" documentary that i used to make my edit had a better a picture with less artifacts, although it was only about one minute
By the way there is another highlight on this DVD set - John Lennon singing "Hey Jude" during the end titles. It was previously available only as audio.
