June Foray is still around at age 99, and has done a voluminous portfolio of voices, including work for Warner Bros., Stan Freberg and...yes, Mark Evanier. Among Bill Scott's other voices were Dudley Do-Right of the Mounties, as well as Mr. Peabody which I mention because -- listening to his real voice here -- Mr. Peabody seems to be a pretty darn close overlap.
