Watch footage from Pulp and Blur shows, then come back.
What is a reunion for reunions sake? Why do they not "deserve" a headline slot simply because they have reformed? It's usually the other way around.
Idles have sold out Manc Apollo twice and close to selling it a third time, that's around 10k over 3 nights. Chemical Brothers played Manc Arena on the back of an album, Pulp would sell it out without an album, Idles would also do the same.
Not a clue what point you're trying to make.
