If the Stoat has to go through all that performance, and he'd be on his own without his biracial walking-frame, I really can't see him going. Likewise she'd be on her own and no cameras to catch the silicone drip from her boss-eye.
I'd guess they'll stay away, and mount a huge rival Spectacle in their multi-million 16 toilets for the Ffark birthday for close family and Hollyweird A-listers.

Snakebite, Tyler Perry, SkidMarkus the Pimp, Snakebite, Doris Scragend, T. Perry, Scrofulous Aphid, Tyler, Jug-eared Boozy, and HarriNooNoo who will Photoshop the pictures for the Arsewhipes website.
The photoshops will show Tit Clooney cuddling Legless, Beyonce lighting the candles, Obama with Ffark on his knee, Reese hugging Snakebite and Jen, Brad hugging the Stoat, Welby, Kamala Harris, Rishi Sunak, Thunberg, and Biden drooling into a bowl of muesli.
