He made some really great songs, including Le Sud de la Louisiane and Year of '57. Brought a bit of bluegrass style to Cajun music. Hosted Laissez le Bon Temps Rouler on TV in the 70s and 80s. Did a lot of charitable work, too.
He was also a fixture on television years before that on Sundays in Lafayette with Happy Fats and Ambroise Thibodeaux. I've always loved his voice a great deal.
