Wouldn't expect to hear anything for a while. Stones tours might get pencilled in well in advance, but they tend to get announced much later than other big shows.
Probably looking at early next year for that announcement.
Well I assume if the rumours are true that the Stones are back on tour and planning to return to the UK for the first time in a little while next year that we'll hear something tangible soon.
Even if it is slightly strange that the big announcement for a stadium tour this week was Stereophonics.
Glastonbury/HP and Glastonbury/Finsbury I think are combos that have both been done tbf. But yeah an IOW/Glasto/Finsbury/Cardiff run feels like oversaturation for Stereos. So they've probably made their bed for this year.
