Thanks for the tip. Preordered!

Thanks. That's very helpful... Was Ellington the only one who did the Treasury Shows? I have all of those volumes and really like them. 

The Goodman estate has kept some very important broadcasts from being released including some with Charlie Christian and Lester Young (not together)  from the Savory Collection.  I wrote their lawyers an e-mail and actually got a response.  They're just being jerks . As  I mentioned in my e-mail to them, they're even leaving money on the table in that- deservedly or not- Goodman's name is listed as composer on many of the compositions and jams so the estate would be paid for any broadcasts or streams of the material.
