Darn, I thought this was going to be live music - but it looks like some live concert footage dubbed over using the studio version of the song post edit.
Her lips don't even come close to lining up with the music. That's unfortunate.

Yes sorry its a bit heartbreaking but I love watching performers from the era of real music without autotuning.

True enough, Watching the vintage footage is always interesting. and ya, It's real music from people who could actually play music. That's always the first thing I notice when I see this stuff. It's more about the music and way less about image, at least by today's standards.
These days, it's look good first, play music second.

Not the same vid but a live performance in 77

And for those that want a more modern take, Alice in Chains, Gretchen Wilson and Nancy Wilson play Barracuda together

Studio track on that one too. Not sure I've seen a truly live Barracuda. The Magic Man I posted recently had live vocals, that was sweet.

Ah bugger, I had a skip through to see if there were any obvious lip synch mishaps but it seemed to be kosher... =\

This is my last stab... =D
