I'm a fan but I've never seen Tool and I doubt I ever will, only because there are too many johnny-come-lately fans in Toronto. They are huge here when the album or tour comes around, then there's a three or four year lull in between when everyone moves onto whoever else is popular, then the tour comes back around and everyone is all of a sudden a huge Tool fan again.
That and they'd never play my personal favorite song; Ticks & Leeches
05/31 -- Decibel Tour
08/09 -- Danzig
