I'm sure Rodger can answer all your questions on his
very own forum. Seems to be a cool place althougth I havent been there in a bit and he has answered a few posts regarding Steely Dan in detail. Just do a search on his forum and type in 'Steely Dan'.
Also some more info
on his website.
There are some interviews etc where he talks about Steely Dan.
Hope that helps. Maybe Jules can get him as a guest Mod. thumbsup
