20 million people applied for tickets for the Zep reunion show (including me, I didn't get one)
20 million times say $200/ticket = $4B assuming they could stay out long enough to play to that many people.
A Zeppelin reunion is by far the most sought after show ever , more so even than a Floyd reunion.
Yes, John Bonham is dead, we know, but call it what you will, a Zep reunion tour would eat 360 for lunch.
LOL, there may have been 20 million applications, but there were not 20 million people. It is only the dream of dedicated or near religiously devoted Zep fans that they would eat 360 for lunch and then tour the rest of the Universe.
Its easy to dream and pretend that one's long defunct beloved artist will part the seas and move mountains if they returned, but reality of what would happen is far different.
First, there was the demand levels the band had back when they were a band. Was Led Zeppelin the most in demand band back in the late 70s? Well, concert stats show that The Rolling Stones, Pink Floyd, and even at the time Aerosmith did shows and tours with as large or larger attendance.
Second, the drummer is no longer here meaning a true reunion is impossible. That is a fact that decreases demand.
Third, after 33 years, there are people that are no longer interested in going to events like that or perhaps are just not interested in Zep anymore enough to pay $100 dollars a ticket or greater to see them in concert. Things change, and it may not be possible to repeat a bands past glories after so much time away.
No doubt the Legend of the band is huge, but that does not automatically translate into record breaking boxoffice results. This often happens to other artist, although on a different and smaller scale.
