He is indeed, but not a Series 1. It's a late Big B with the 6" bell, likely stamped as a 156. Had to (gladly) sit through the video to catch just the right angle (around 6:30) when someone took a picture and lit up the engraving to be sure.http://forum.saxontheweb.net/showthread.php?153861-FA-Buescher-Aristocrat-Series-I-Stencil-(tenor)!
In case you're interested, I have a Series I Crat stencil for auction.
It plays as is, but of course needs an overhaul. Selling it because I'm an alto guy. Budget for a case as the one it's with is horrible. Absolutely horrible. Monster horn.
Is Joe Lovano playing one of them here?
