I hope everyone reads the letter because it gives the origin of the unopened records story and also the record recitals that Burnie allegedly used to give ending with a Busse trumpet solo that he mistook for Bix. As you can see, in both cases the truth must have been enhanced for journalistic effect in "Bix Man and Legend"
There is a world of difference between Bix arriving home and finding all his records unopened in their mailing boxes, and what it now seems actually happened: i.e. Esten Spurrier visiting Burnie after Bix had died and commenting that it looked as if the records had not been played. Actually, as anyone who collects 78s will know, a mint 78 still looks mint after several playings ! And the fact that Burnie played When Day is Done as an example of Bix at his best does not mean that he used to play a selection of records to all his visitors finishing up with this one.
