Big thanks from me as well - downloading the lot, a great resource to have.
A cursory random scan of 1940s issues has stories with Django Reinhardt reported reputedly killed during WW2, Buddy Rich joining the USMC and a small classified ad from a start-up company called Blue Note Records on Lexington Ave advertising records for sale ! The Petrillo Organisation also gets lots of print space (no surprise I guess).
This gem from Dec 1959:
"During Louis Hayes’ drum solo, Shostakovich and Dankevich leaned forrward and watched the rim shots and rolls with concentration, like a couple of visiting American businessmen. Cannonball’s own quotes from numerous classical composers (in the course of his solos) didn't draw a smile."
