I didn't find George Sanders in the obit books, but I did find a good match in the Chattanooga Library obit collection. It says his name was George Beecher Sanders and the obit appeared in the Chattanooga Times on March 10, 1965.
Here's a link: http://www.hctgs.org/obituary_database.htm
Digital copies by email are $5 for the first 1-4 obits, or $5.50 by postal mail.
Hope that helps you in your search!
