the grandfather from "I'll Fly Away" - he has that old black man voice w/ deep bass that would fit the character better, plus his voice is anonymous enough that you would just think of him as Granddad Freeman instead of picturing John Witherspoon. Witherspoon is funny but his voice kind of turns Granddad into his typical Boomerang/Friday character, which is not how I really picture Mr. Freeman.
