Hold back headliners, scaring people who want live sets off, those people buy tickets for other fests and then they release them
Seems a bit silly!
Due to my teenagers Kpop era I have actually seen Sabrina before.
While she wasn't at all memorable she at least escaped being described as the 'Btec Taylor Swift' as Maisie Peters was by the waspish 15 year olds.
