The backup singer is Lori Nicks, Stevie's longtime backup singer, close friend, and future sister in-law.

As some have mentioned, the makeup artist was Stevie's longtime best friend Robin Anderson, who was diagnosed with leukemia in 1981, not long after this was filmed.

[quote]While in remission, Robin discovered that she and her husband, Kim, were expecting a child. Robin’s cancer returned, however, and she discontinued treatment. “She knew that she was going to die,” Nicks says in the clip, “and she wanted to leave that baby behind. She wanted something to be left from her.”

[quote]Soon after Robin’s child, Matthew, was born, Robin passed away. Nicks was devastated by her best friend’s death, and the grief sent the singer on a mission. “I wanted that baby,” she says in the clip. “I convinced Kim, and three months after Robin died, we got married.”

[quote]Nicks says she thought it was what Robin would have wanted, but it soon became clear to her that not everyone agreed with the decision. “It just blew up in our faces,” says Nicks — who now understands why others disapproved. “It was so the wrong thing. To take Matthew and [Robin’s] husband was so beyond insane.”

The marriage ended in 1982 and Stevie was not allowed to see Matthew for many years in spite of her being his Godmother.

The album version is very different from this raw version. For the 1983 album version of Wild Heart, Nicks wrote an intro dedicated to Robin. She also changed the background instrumentals so that she would have full writing credit for the song instead of having to share those credits with Lindsay Buckingham and Richard Dashut, who wrote and produced the instrumentals for this demo version.

This impromptu performance was filmed at Annie Leibovitz's studio. The photos were for the September 1981 issue of Rolling Stone.
