I find the whole thing going ahead now - whether Hannah is involved or not - rather crass. If it was a one-off gig, or even scaled back to a few dates in key cities around the UK, I think framing it as a tribute to Paul would feel a bit more tactful.
I do perhaps understand why they may feel the need to push ahead as much as Hannah clearly didn't. But more than anything, it's the thought of them flogging pricey merchandise to fans for a tour that's been rebranded with such a tragic subtext that feels unconscionable.
