I think with Foos they get away with some underwhelming second headliners like Central Cee because they can be shoved under them and it looks about right whilst still guaranteeing tickets will sell. Get rid of Foos or an act with the equivalent status and it shows up how weak those are.
I know it won’t be but if MCR, BMTH and Chappell Roan are three of the headliners that’s actually insane. Central Cee fill the other three slots for all I care 😂
