Not sure if that's Hoyt Axton (it could be) but it's nice to see ignorant yankees haven't gotten smart enough to change their opinions of the south since this ad aired.
That's Hoyt Axton, I believe. A songwriter of many different genres, and widely recorded by many of music's biggest stars. Definitely not someone who had to "settle with a GED".
"Redneck" is better defined by "The Dukes of Hazzard", not a smooth voice like Axton's.
