Ok, better question - is there an Afi song you think TH couldn't do well?

Oh of course. I don't see Bill EVER being able to do much of the vocal style straight up to Black Sails, though he could probably do the REALLY early stuff (Rolling Balls anyone? Bwahah).

And just in general, Tom is not up to snuff as a guitarist to be able to do any of Jade's solo work -- they'd have to use electronic fill or something.

Anything Havok really screams on.... no.
I mean, can you hear him trying to do Kill Caustic or Death of Seasons, or Affliction? Please.

Kid just doesn't have it in him yet. And frankly if he's as prone to vocal cord injury as he seems, needing surgery so early on, he shouldn't ever try. At least not without a LOT of training.

Have at it.
