The great John Cleary does "Tipitina", filmed live at Chickie Wah Wah in New Orleans last December, a "Sitting In" video from ABIS Productions.
As a little lagniappe: an hour-plus-long (1:07:14) seminar on the New Orleans piano tradition that Cleary delivered at Loyola University in 2012. He discusses major figures like James Booker, Professor Longhair and Jelly Roll Morton, and places their work in the larger context of the musical traditions of the Caribbean rim. (Note: this video was recorded at low levels, so you'll likely have to turn up the volume.) Very interesting if you've got the time!
