What band or bands can still exist with only one original member?

i asked a question earlier about bands who can exist with at least 2 original members and someone pointed out motorhead,even though there is only 1 original member,lemmy.i thought about this and i realized "my god,this guy's right,as long as there's lemmy,there will always be motor head."here are a couple of my examples,whitesnake and winger.as long as you have coverdale it will always be whitesnake,it doesn't matter who he has playing with him,same thing for winger,as long as you have kip it will still be winger or even dokken,as long as you have don dokken it will be dokken or lynch mob,as long as you have george lynch it will be lynch mob.well you get the idea.
