It could have been a buescher. I was really surprised that he got such a great tone when he took so little mouthpiece. I was also surprised that he puffed his cheeks (a controversial topic in itself). He doesn't seem to be using circular breathing. But, it is a fabulous take. Dark Eyes (unloved thesis)

Zoot usually played an old Selmer Super Sax (or Cigar Cutter) with a black rubber Brilhart. He was one of my earliest influences and I've listened to a lot of his work. He started out with Woody Herman's big band, I think, then had a quartet for years in the 1950's, played with Gerry Mulligan's various groups at times - notably with The Concert Jazz Band in the early 1960's - and played with many small groups in the 1970's - among many other associations. Zoot is known as a swinger, in that he had an inate sense of rhythm that did not get lost despite the improvisational complexity. Glad you all remember my favorite jazz tenor man.
