I don't blame the pros for saying yes to their own show because it must be tempting if they're offered the chance to headline, but it sure is risky in the current climate. And if something gets cancelled last minute due to poor sales, I guess that's a lot of crew that miss out on pay too.
I had a quick look at ticket sales for some venues and from this very quick, unscientific study I gathered:
Decent/ok-ish sales : Gio, Anton, Gorka and Karen (and maybe Gio selling less that I would have thought? Gorka and Karen actually outselling him a bit in Glasgow)
Surprisingly not great: Dianne and Vito (I know it's early days but I checked a few venues and there doesn't seem to be a huge demand)
A runaway success and nearly sold out in a few places: The Legends of Strictly! (I mean, I guess that line up is irresistible to older Strictly fans? Gio could never)
There is a lot of love for Amy right now, so I reckon they might do ok
