He says he can't remember things that happened last year as well as he can some stuff from 50 years ago — like a conversation he had with the subject of his new album, Louis Armstrong.
However, Dr. John had no trouble recounting a night 10 years ago when he played the Dakota Jazz Club in Minneapolis.
"I was on the phone before the show, telling my spouse to get the hell out of New Orleans," the real-life Mac Rebennack recalled. "It was a very emotional night. A real drag."
That Aug. 29, 2005, show fell on the night Hurricane Katrina went from bad to catastrophic, wiping out wide swaths of the city that counts Dr. John among its most revered ambassadors.
The mood should be a 180-degree turnaround Saturday when Dr. John returns to town to christen the St. Paul Saints' new downtown ballpark, CHS Field. Part of the Twin Cities Jazz Festival, his special 3:30 p.m. performance is a tryout for using the midsize stadium as a music venue.
Talking by phone during an East Coast jaunt two weeks ago, Rebennack was surprised to learn that one of the co-owners of the Saints team is actor Bill Murray, with whom he recently finished another kind of gig.
"We were partners in this new 'Jungle Book' flick," he said, referring to voiceover work for an upcoming live-action remake of the Disney classic.
Asked what it was like to work with Murray, the good Doctor gave an emphatic one-word answer in his unmistakably gravel-gritty, swamp-froggy voice: "Easy." He sprinkled some more colorful words throughout the interview: "acupuncturation" for what keeps him in shape to perform at 74; and "recentarily" during a conversation about Joe Glaser, the manager/agent he shared with Armstrong.
