When the Grateful Dead hired Vince Welnick, do you think they just openly said, “Please don’t die. Like, um, everyone else that’s done the  exact job you’re about to do. And whom you even physically resemble, to make it creeper-still. In fact, don’t even think of this as a keyboard gig, think of it as a not-dying gig where you also play keyboards. But keyboards really, with this kind of abysmal track record, should be at most secondary to your every single thought from the time you sign this contract until your untimely, yet entirely predictable death some time in the near next decade. Please at all times try not to be dying. Thank you, and put on a hat.”
