FYI, Ian, re your note at the bottom of the page for volume 1 regarding "Hot and Bothered" ("*The version of Hot and Bothered currently available on Volume 1 is, in fact, the version recorded on 12 June, 1930 and repeated on Volume 3 (see here)..."): I downloaded Volume 1 on October 13th, and Sony has replaced "Hot and Bothered" with the correct 21 October, 1928 version. At least to my ears, the two versions sound very different. I hope this helps.
