My perception is that ALW has a sort of mental idea about what, this time, Joseph should be and then in the sing-off he chooses the one who most matches this - not that they are actually 'right', just that, of the two on offer at that moment, they are a better match to this image. And his image is for a young, poppy Joseph. As a result, after a bit of early clearing out, the musical theatre voices then went whenever they were in the firing line (Johndeep, Seamus, Chris B and Daniel), and the older (or older-seeming) guys (Rob and Craig) followed. Now we're left with three young, poppy guys and Lee. I see the last weeks offering a test of whether ALW sticks to his guns, or else chickens out and eventually goes with Lee (assuming he has a choice, and Lee comes up for a sing-off, which I presume either he or Keith must do in the penultimate programme). I'm not sure if he's 'clueless' exactly, although I certainly don't like his approach to vocal types in this context, since I much prefer a musical theatre voice. I would certainly have much preferred this week's line-up to have had Daniel and the two Chrises, say, over Craig, Lewis and Ben. I do have a fundamental problem with Ben's voice, since I do not find it convincing outside a narrow range of notes and dynamics: his soft singing is colourless and his sustained notes very prone to an intrusive vibrato, as Zoe pointed out - yet both of these are basic to the part of Joseph, whereas there isn't much of the lively song n'dance stuff he is good at.
