I found this rare 1978 interview of her getting off a plane in Dallas with the rest of Fleetwood Mac. It's only about five minutes long but it's got some funny parts in it. You got the starstruck pilot taking pictures through the cockpit window. Meanwhile, the stewardess looked like she couldn't get them off the plane fast enough - they must have put her through hell on that flight. Then the reporter collars Stevie coming off the plane for an interview while the rest the band walks off apparently unnoticed.
Check out the knee high tube socks on some of those guys. That's how you know it's the 70s. Those used to be stylish!
