Hello
I simply ask a question: is it "easier" for a drummer like Chad Cromwell or Pick Withers, Terry Willians or even DC... in concert knowing that he participated in the album and therefore to know the requirements of MK OR like Chris Whitten to land on the tour thus resuming songs created by other drummers? And this by forgetting the tastes of each for such or such drummer... PickW (albums), TerryW (albums, soundtracks), Chad (albums),...
I ask the question and I don't have the answer, but can it play?
It would be a question for Chris or for any professional drummer but, as I see things, it doesn't really matter whether a musician has actually played or not on a record prior playing the songs live. First because recording in a studio is a complete different process than playing live. Beside this, each venue is different. Then, because a pro musician should able to take over any other fella, of course with his / her own style, as good as it gets.
It happened with MK so many times. For instance, Sultans was recorded by Pick and then played live by himself, Terry, Chris, Chad, Danny and Ian. Speedway at Nazareth was recorded by Guy and Jim and was played live by themselves, Geraint and Matt too etc.
The best example of a musician having to replace one another is of course Danny who had to take over Chad on an extreme short notice in 2005. How Danny coped with it who knows
… ? but I bet that Mark sent Danny a recording of the show when he -- Danny -- may have played over it until late at night to learn all songs and be ready on D. Day. A sign of greatness.
