Could be Wilcox, and he's been active through the nineties and into the 21st century! (I've got a great private recording of him backed by Danny D'Imperio and his father, Pete D'Imperio).
Berigan, that was Wilcox on that Bix documentary.
Rank was from Cincinnati and was a presence there in the seventies, and did play in Whiteman's Orchestra (poor guy, simultaneously with Tea!)
