I'd argue it could strengthen his case, if anything, unless those dates are all over the G weekend itself.
Big venue - not sure what the biggest stadium is for concert capacity in London.
The 4 day gap between Irish and French shows, and no belgian date would suggest heavily they will play.
Even more so, that the green day at werchter show is bang in the middle of the 4 day gap in schedule.
Yeah I agree, they’re certainly bigger than Sikth, Cradle of Filth, Lorna Shora, etc. That’s why I think it could be that their management have seen the poster and requested a logo. I’d suspect they’re fourth on the main stage and adding the logo hasn’t changed their placement.
The bands playing fourth on main are generally bigger than the bands headlining the fourth stage, but don’t traditionally have logos, at least on the full lineup posters. Baby Metal and Bowling for Soup both had logos on the first announcement for 24, but then not on the full lineup.
