I think the Bassey/Winehouse comparison is a good one, and you can see that especially in the way Amy is being talked up as the potential singe of the next Bond theme.

Ian Anderson's definition of what he does and doesn't want to cover in his magazine matters really to no one other than him and those who choose to buy it. It's just that occasionally certain folk try to impose that definition in other places as a constraint on what should be discussed there too. Anyway, their attempts at trying to tell us what is "rooted in tradition" if it is by one artist whose they like and not if it is more or less the same song by an artist whose they don't can often be most amusing.
