Of course they would headline. Given their long absence they would be even more hyped than before.
They played Werchter 6 times before during 1996-2017.
Just out of interest, what do you think the kitsch Boss songs are? I have suspected this (love him btw) but rarely see folk bold enough to say it hahaha And well done on the Fender stadium chat, that was you sharing that wasn't it? I have a great pal in Newcastle and SJP could be a laugh but I don't know if a whole Fender show would be a bit dull (my pal in Newcastle is quite the muso).
