I became aware of Reggie Hall at the 2006 French Quarter Festival and NO Jazz Festival, where he appeared as bandleader of "Reggie Hall and the Twilighters."

Reggie stood near the front of the stage behind his keyboard, but did not "front" the band as vocalist. His featured singer was absolutely terrific, a visibly aged dude with tremendous vocal chops in the blues-shouter tradition. I wish I could remember his name ~ he had at least two nicknames, in parentheses, between his real first and last names, one of which referred to his signature song, something about "doin' the dog."

For the rest of that summer, Reggie and the Twilighters and their featured singer made numerous appearances, but I haven't heard about any of them since. My best guess is that at least one key person may have passed away ~ if not Reggie himself, perhaps the singer, who really did look to be on his last legs two years ago. Even though he was able to "deliver the goods" very effectively as a vocalist, he looked pretty old and feeble offstage, and especially exhausted by the end of each show.

The most common reason for New Orleans musicians disappearing from the local scene is displacement by the levee-failure floods that occurred in the wake of Hurricane Katrina, but that can't be blamed for this band's fairly sudden absence. They actually made their big splash, appearing at multiple local festivals, during the spring and summer immediately after Katrina.

I understand that Reggie toured with Fats for many years. Dave Batholomew, who co-wrote most of Fats' hits, wrote all the arrangements, etc., is generally credited as Fats' lifelong "bandleader," but I don't know that he always went on the road with his protege ~ brother-in-law Reggie may have played that role, at least on a few tours.

A website called "MunckMusic" has CDs for sale of live shows from a number of different bands and events. Here's a link to their page of New Orleans Jazz Festival recordings, including the 2006 appearance of Reggie and the Twilighters:
