Also, this it might be useful to note that this was filmed at Dallas Love Field and not D/FW International as I have seen the video listed elsewhere with incorrect attribution of location because of the confusion with the news station identifier (KDFW) and the airport, which uses the same letters for its aviation identifier.
Thanks for spotting those errors! Upon further investigation, it looks like they were arriving on July 21st for their July 23rd performance with the Steve Miller Band at the Cotton Bowl. Thank you so much for pointing that out to us, we want our site to be as accurate as possible!
This is not 1980. The band members" looks aren"t right for that time period. This is more likely summer of 1978 at the tail end of the Rumours tour. Also, the footage you have labeled 'Lindsey Buckingham gives fans autographs' is actually of Mick Fleetwood giving fans autographs. Hope this is helpful.
