Yeah, I do get your point, but I just don't see a problem in extending their setlists. Why don't they play their normal "boring" set and add 2-3 old songs?! "With You" or "Figure.09" for example are normal songs that are on the same records as "In The End" or "Numb" and I'm sure lots of people know them even if they aren't hardcore fans.
I would be happy with this solution and I know a lot of others would be too. Do you remember the Paris show? By adding A Place For My Head to the set, it suddenly became 'the best setlist ever'...
And I'm paying 70€ for one ticket, I can expect a longer setlist. If Chester can't do these songs anymore, they should lower the prices...
