Perhaps touring with Bob, the fact they haven't been top bill and they haven't been playing the hits like Sultans etc. has rejuvenated them.
Comparing Marks performances between last year and this is like chalk and cheese. Last year seemed ill-conceived and without any practice with Mark starting the tour in a manner that, frankly scared me for his future. Now he's better that he's been in many years. Something different has been done for this tour that's for sure. Whatever, good for you Mark and keep it up!
