I agree with you, Quizzaciously, that MK plays much better sitting down. The 2010 tour is evidence of this and it is my favourite tour.
Yesterday I drove to work while listening the Madrid 2010 digital download that came with Privateering, and I was thinking how exceptional was MK guitar playing in those songs, and I recall that it was played seated...
I totally see MK doing a small numbers of shows with his "local band", Robbie, Marcus or David Bronze, Guy, another keyboard player (Geraint?), the Macs and Ian, in venues like the RAH, in a more intimate way.
But I don't foresee him doing it until 2023, unless there are a sum of great coincidences and in the same week or two weeks his management find some available venues to do some dates in 2022... That I hope so!
