When I saw them in London Gary Husband played drums - nailed Buford and Bozzio's stuff very tastefully. Machacek played amazingly, too. A memorable night...I don't think they would replace Bruford, as Bozzio did not replace Bruford un U.K.
All have just strong musical characters (and I mean that in a very good way of course, no one wants a copycat).
But then I agree on the fact Minneman and Harrison would be a perfect math to revisit U.K. drumming (well, are, for Minneman).
