It's nothing new and I'm sure many have heard this before but I just came across this show on YouTube and I had a delight listening to it. Not for the band but for the three people recording the show and giving their commentary.
This is like a look into what the experience must of been like. There is something I really enjoyed about this and found...wholesome. I wasn't around then so hearing people react to things in the concert back then is interesting. Listening to this reminds me why I love KISS so much. I become oddly invested in these three people's lives for an hour and 18 minutes. They debate when to take photos of the band, try to predict the next songs, get excited when they play "New York Groove" and react in amusing ways all around. As far as KISS goes the only notable error was Paul's mic not working in the beginning of "KOTNTW", otherwise it sounds like a good concert from what you can make out.
I love hearing these genuine reactions, maybe this is a weird topic but hey. This made me happy so I thought I'd share it in case other people haven't come across it before

I will point out the highlights.
10:14 - The guy says "What's next? Who cares it's gonna be great anyway" and then he gets excited when he realizes their gonna play "Dr. Love"
18:16 - When Gene breathes fire. The guy reacts when Gene brings the fire out and then explodes when he gets a photo of Gene doing it. When the guy says shit the girl goes "watch it my Mother's gonna-" implying the show is being recorded to show her Mom.
14:00 - The girl is waiting for "New York Groove" and at 19:04 everyone gets excited when they play it. The girl is amazed by Ace's light up guitar.
22:28 - The two guys are impressed by Ace's solo
23:36 - The guy reacts to Paul's rather creepy banter
41:44 - The one guy who's clearly seen KISS before waits for Gene to fly but it doesn't happen in this show
53:08 - Lots of amusing bits here before "Black Diamond". You hear someone in the crowd with an arm horn
1:02:00 - "My ears hurt, I went deaf for a few seconds" "It's worth it"
1:02:16 - The guy starts cursing at the people leaving the concert before the encores. This is the funniest part "They're gonna miss the national anthem of Rock 'n Roll!"
