Oooh, that is an interesting question. Wally wold make for a very interesting speaker, if he's up for it. What a perspective his years lend upon the various changes in our craft.
Others that might be concidered would be a few folks that I have personally seen do a demonstration and I noted that some of the individuals just have that ability to captivate an audience and I am not just talking about the lathe running! Ones that I found interesting were Doug Fisher (he has traveled the world), Jimmy Clewes (great sense of humor and can always give a good "tale"), Ellsworth is just a given. David could most certainly enlighten the group.
Good luck with your search and let us knwo how it goes.
