Les and El Greko...I take your point about Kathryn's lack of vocal range, but I have a couple of her CD's and her voice is very good.
In fact her version of "Ned on the hill" is my all time favourite.

Surely her pregancy must have had much to do with her vocal problems.
I had a vision of her going for a high note and wiping out the first two rows of the audiance.

At least she went for traditional and meaningful material, not the pretentious stuff we saw from some of the others.

Cant agree about Eliza though, seems to be "part of the problem not part of a solution"
