The late, the great Clifton Chenier, live and on stage at the New Orleans Jazz and Heritage Festival playing Cochon pour toi (or I’m a hog for you).  Looks like the late 1970s, but not 1975.  Here’s a photo of him from 1975. But the small stage, the crowd, and the shot of the grandstand in the background, definitely harkens to that era.  And Buckwheat Zydeco (Stanley Dural) is playing organ.  That’s probably Blind John Hart on saxophone.   What a compliment to pay a woman, “I’m a hog for you!”
