I have some of the bootlegs of Zevon and Jill doing covers: most notably Johnny Cash/June Carter's "Jackson." I enjoy them.
Jordan may not want his father remembered for "Werewolves," but, if he is not careful, he'll end up insuring that his father is barely remembered at all.
Personally, if "Werewolves" was to be covered, I would have gone with the Dead or Lou Reed.
And John Hiatt doing something, perhaps "Bed of Coals," would have been brilliant.
