yeah, if we start talking about duets/harmonies, we'll just have to list every track the cat opens his mouth on.
same with the bootleg/guest appearance territory - the list of beautiful stuff no one's mentioned yet is vast.
some that i've never heard and am yearning to are the Keith LV renditions of Rip This Joint and Loving Cup, and the early takes of Can't Be Seen.
