Funny you started this thread. There has been a lot of talk about Phish covering a Steely Dan album for Halloween. Complete speculation, but quite a few people seem to be on board. Come on Pretzel Logic...
Great news, even if it is just speculation. I hope it materializes.
My personal choice would be "Countdown to Ecstasy", although they can't go wrong with any of the first 7 album releases ("Two Against Nature" hasn't quite grown on me yet, and I have never listened to "Everything Must Go").
I'd love to hear Trey nail the guitar parts on both "My Old School" and "Bodhisattva".
Did they have a horn section on stage when they played Little Feat's "Waiting for Columbus" in its entirety?
