I just looked at the level of ticket sales for the UK tour.
The sales are more than average: with the inflation crisis and the poverty that is setting in, the venues are filled to about 60%.
The lack of new material (even if the album is coming) and the very high price of the tickets are an obvious brake. And Peter doesn't have the same impact on the crowds as Genesis.
I think he'll still manage to fill up the venues by May.
Sales are much better on the rest of the European tour.
