Dennis McGee: Honorary Dean of Cajun Music (1982) 

Dennis McGee is named an Honorary Dean of Cajun Music by the president of the University of Southwestern Louisiana (now the University of Louisiana at Lafayette) and performs on the 50-yard line before a Ragin' Cajuns football game against West Texas, September 19, 1982. He's joined by his brother-in-law and long-time secondeur Sady Courville and Michael Doucet on fiddles, Preston Manuel on guitar.
This edit (it's unclear whether there was more shot at the event) wasn't shot by Alan Lomax, but a further-edited portion of it appears in his American Patchwork film "Cajun Country." (Streaming online here: www.folkstreams.net/film,125.) Lomax remarks therein that "nothing like this has ever occurred anywhere else in the country, but it ought to."
