Man, that's a drag. I used to love seeing him sit in for Ed Shaughnessy in the Tonight Show Band, 'cause they'd always let the band do a number so Louie could show off his chops. And I'm amazed that he recorded his last album last year--incredible.
Interesting that they're burying him in his hometown of Moline, IL. Seems like he oughta be next to Pearlie Mae, but she's buried in West Chester, Pennsylvania according to her Wikipedia bio.
