This video just popped up on my computer. While I could not hear all of the conversation between Mick and Keith, it does seem that the announcement was not to take place a few days ago at a concert but at an early date in January 2022. Keith was heard reminding Mick that this was not to be the big day.
If there's a new album lets hope Ghost Town isnt on it ... Yep best song of the Covid times if theres such an award but its a glum reminder of what weve all had to live through ...
