If the West Coast had "fixed" sound mix, a) it is reprehensible as this was supposed to be a LIVE show, warts and all, and b) the mix I'm hearing is one of the worst ever with vocals buried under the orchestra - if it was worse, I can't even imagine it.
Has to be the same, then.
About halfway through the broadcast I tried switching my receiver over from Pro Logic or whatever it was defaulting to, to plain old L/R stereo, and oddly enough it tightened things up and brought the vocals into better balance with the orchestra. Still ugly, though, and I found it more pleasing in general to keep it on the surround setting.
There's an interview with a producer or someone at the network, in which they admitted there was one (1) - count 'em - audio person at the controls.
