Stevie was great last night. I love her in the long skirts, wish she would wear them on stage. And while it was lip synced, it was not the original Fleetwood Mac vocal. When artists make albums they do a special one called a "TV Mix" which has the instruments and background vocals, but does not have the lead vocal. They do this because lots of TV shows they may do to promote a song don't have the budget or technical facilities to have the music filmed live. And lots of artists prefer to do TV shows this way. Fleetwood Mac and Stevie are not those kind of artists, they always prefer to perform totally live. But the record companies still make all artists do a TV Mix of any potential single.
You could tell on the show last night that Stevie sang the vocal in a studio for this show, as it was a different vocal from the original. Then they had her lip sync in while being filmed. And I thought her new vocal was very good. She sings Seven Wonders quite well at this age, some 27 years or so since the original was recorded. It made me wish Fleetwood Mac would do it in concert when they tour again. Last year on tour Sisters Of The Moon did not sound anywhere near what it used to sound like live, they should take it out of the set and but Seven Wonders back in.
