I think it starts with some sort of hype video that kind of highlights the history leading up to today… Then the guys talking about how this came together and/or a short behind the scenes documentary about the making of the new song. A nice little segment or interview with the new singer to get to know them, and how they got here. tour/show announcements, music video, and then (and this is purely wishful thinking) maybe an album announcement with details on bundles etc. and then some sort of short q and a.. all of that plus them playing 4-5 songs either at the start, the end, or maybe even sprinkled throughout the whole show kind of like a Howard stern interview.
idk why, I just don’t see them playing a ton of songs.. at least not on the live stream, maybe the crowd there will get more.
edit: also didn’t know the show was 90 minutes long. Is that the length for the actual stream? I’m imagining the live stream being 30-45ish minutes, with another 45 minutes just for the live crowd, that might include an extra 3-4 songs and a photo op.
