God, I've enjoyed reading this thread so much.
I agree 100% that Diana has single-handedly reintroduced yodelling to Britain, for which she should be FLOGGED with the very same hairbrush she has been avoiding actually using on her hair.
Poor EOWIAIUEAN - he's a bit pointless really. His voice is just sort of nothing, although I think he's quite cute-looking in the same way puppies can be. You watch - he'll be selling toilet paper before we know it.
JLS - they've let the side down lately, but I think they sound great when they get their act together.
Ruth's voice and presentation I thought had really developed, and I was both shocked and disappointed that she was voted off. Should have been Diana for that dreadful rendition of Everybody Hurts ... my ears certainly did. I hope REM sues her for doing that to their lovely song. Or EOWAIEEEN for being so very forgettable.
Alex sings well and puts on a good show.
And that's my tuppence worth.
