I'm going to put my comment in spoiler tags even though I can't see how it could be true at this specific moment in time...
Spoiler
On the red button interactive service, under "Josephs voted out" Lee's name is there! They are only listing Ben, Lewis, Keith and Craig as the four possible Josephs.
Daydream Believer? Oh for god's sake, just putting the word "dream" in a song's title does not mean it is one through which you can convey dreaminess. I give up!
Mirage, you'll be lucky to get them all doing show tunes until the final when they will sing something from Joseph but knowing this ridiculous programme, even then it'll probably be the Narrator's songs they are given!
