If you've read the press material and the articles published so far there's not much new stuff mantioned in the interview. With one big exception:
When asked if he'll do any songs from the album on the upcoming Steely Dan tour he says no and explains why.
Walter also mentions his favourite track from Circus Money and why it is his favourite.
Well worth a listen. Walter's entertaining as always.
UPDATE June 6: Here's the link to another radio interview online kindly posted by Dimension Skipper in the comments:
"Not as interesting, but here's another 10 minute by-phone interview Walter did on WMGK recently (May 28th) with long-time rock DJ John DeBella on Classic Rock WMGK, 102.9 in Philadelphia."Walter sounds in a good mood and is able to rephrase the answers to some familiar questions.
