I have heard about this tour pitty they do the USA only. I hope they will come to the EU next year, but I would never pay 250$ just to see them(at least it would be a few day festival with a lot of bands included).
Farewell tours are a scam most of the time. Ozzy first farewell tour "No more tours" from 1993 -> he is still here. Scorpions farewell tour from 2012 -> they are still here.
From my experience farewell tours often mean just a longer break from touring.
I’m sure you can see this concert for less but the venue and seats I wanted were $250. Some were more some less. I saw Ozzys farewell and it was Ok. It’s kind of fun to see some bands past their prime just to say you were there. I can afford it I just don’t know if they can still perform.
Nothing strange!
Old Rock and Roll stars are still active like Jerry Lee Lewis, Little Richard => they are in their late 80's. I wish i could see them someday but they very rarely go touring outside the USA. B.B King, he played live shows until his very death at age of 90. Those guys were the inspiration for the rolling stones and the Beatles and you can still go and see them in 2020 how can you explain that? The only band that I can recall which really finished their career after their farewell tour are Ramones, They made their last tour in 1996 and they never toured again. Maybe cause they started dying 1 by 1 in a few years after.
About the show you are going to see:
I have seen only def Leppard 2 times from this line-up and i have to say you will not regret it. They play even better than in their prime I must say(I'm assuming that only from live recordings). They are one in a few bands that are immortal and don't get affected by their age really. especially their singer is in a great shape. There is a reason for them finishing every concert with "... And there will be the next time"
Again I really envy you that you can go there especially for Joan Jet cause she really rarely goes outside the USA.
