Thanks for your update and your explanation.
Even if MK would just play some shows in the UK to promote the new album, the decision would have been made by now and musicians, venues, roadies and sound technicians would have been booked by now. If it won't be simply something like "a man, a chair and a guitar", it can't be short-term planning. MK knows what he wants and he is planning well. He is a pro.
Well, there is no need of so much advance for a couple of shows, think about the showcases MK uses to play to promote gigs, he has technicians in his own studio at hand , but yes, a little anticipation is needed, and there are always musicians that can be available, for example, for a bass player, if Glenn Worf is busy with sessions, he can call Marcus Cliffe, David bronze or Ewan Vernel, which is what he does for the showcases, same goes for the rest of musicians.
Planning some one off shows is not the same than planning a tour, but yes, there is some anticipation needed, and my guess is if they have booked venues just in case, they might had booked the musicians just in case, because as far as I know, MK is determinated to not play live, and they know for sure it means no touring, but they have hopes he would do some shows to promote the record, if there are proper gigs in a proper venue, the better, if not, they might be showcases, in that case, I hope there is a chance to buy tickets.
I also guess his band mates, Guy, John, Mike, the Americans, when talking to MK and with extra care and sensibility, they try to convince him to play live again, but in the end, is MK who has the last word.
