An awful lot of retro footage from the very beginning of HOTE looks like it was taken that night - for example, Joe wears the same Illinois shirt throughout and their hair and general appearance of most of them is identical. There's a lot of behind the scenes stuff like the curtain being lifted and them messing about in a rehearsal, so I'm not sure why they would go to all that length to film throughout the day then only film half of the actual production. Seems like a half-baked job. From what I can tell BOML was the final song that night, not TIE [1], so the film has been manipulated to some degree.

[1] - They leave the stage far too rapidly for TIE to be the last song, plus there is footage (and a really famous photo too I believe) of them all standing together to take a bow, Henley wearing an acoustic guitar. I know of no other song that Henley played guitar on back in the HC-era, so can only assume it's for BOML.
