I seem to write this in ever Smiths related thread, but I can't recommend the book 'How Soon Is Never?' by Marc Spitz highly enough. It's an extremely entertaining "fictional take" on his real life attempt at getting The Smiths back together that any Smiths fan will likely have a blast reading.
Thanks I'll have to keep an eye out for that.
He most certainly is not pretentious or deluded, he's just different, shy and introverted. In most interviews he might come across as awkward, purely because I think he is. Search on Youtube for a recent in-depth interview with Zane Lowe who really gets him to relax and open up a lot more than I've seen in other interviews.
