I asume the one by the center stage is the one for the sax, trumpet solos. Which was when I was working for the Dan. The other close to Herington I asume is the one that WB used to use during his time with them and I also assume that at least Fagen as respect for WB (which I hope he has a bit of decency left) still put the Mic that Walter used to use to honor his memory. i am not with the Dan anymore since the passing of Waltet due to Fagen getting rid of all Walter camp, so I don’t know much (in the technical stuff) of their touring
