Phew....got my head out of the neck just like Graham's. Mine was exceptionally tight. After tugging at it for awhile and quite sure it won't budge, i dismantled the head from the neck plate and tugged at it some more. It still wont budge. Then i took a mini screw driver put it between the chin the neck, pop it, and voila, it pops up. Now its not as tight but still pretty tight.
