i actually dont doubt that he has throat problems as they have been on tour for quite a while on this tour. i saw them at madison square garden nyc last fall (2006) and recently saw them again in nj (april 27, 2007). you could tell flowers voice is kind of hoarse which happens when you have concert after concert. i remember when i saw u2 at msg this past tour, bono's voice had that "froggy croak" to it and it was no surprise because they had been touring for well over a year. looking at the killers concert schedule, you can see theyve done many dates in a row for a few months now. when the lead singer gets the "froggy croak" voice, it takes more than a single off day for the voice to recover...........
