It's very much a case of piecing a puzzle together, but there is a "nuclear tier secret pop act" with a tour in the pipeline for 2025.
With Oasis, he was told about "A secret AAA band" and "A case of demand impossibly outweighing the demand" so we landed on Oasis.
The pop act I suppose could end up being Beyonce or Lana Del Rey (though I think LDR is an open secret at this point) but my gut tells me Rhianna.
Also, not sure on Fender for Glasto as he'll be doing his own thing. His team may want to not potentially overexpose the Sam Fender live show, especially considering these comparatively small shows in December.
