ChopDawg has a deep, deep library of Larry Munson calls from '66 to '86. He also has calls from '59-66 before Munson came to UGA. Including the Flea Flicker vs. Bama in '65 and the epic thriller vs. Auburn in 1959. For those older calls Ed Thilenius was the play-by-play man.
The sound quality on the old stuff is pretty rough, but what do you expect? It's 50 year old audio that's probably been converted to different tapes and formats a half-dozen times.
Enjoy. Your productivity for the day has been officially ruined.
