Jazz History. Roy Eldridge

(This is as much about YouTube as it is about jazz.)

I'm reading Alyn Shiptons 'A New History of Jazz' in parallel with Ira Glitner's oral history "Swing to Bop'.

This afternoon, it's been about the trumpeter Roy Eldridge, and I come across the following description from Shipton:

This blend of influences is readily apparent on a disc Eldridge and Chu Berry made to commemorate their practice of turning up to play in after-hour clubs.  'Sittin' in', cut for Commodore in November, 1938, opens with the two discussing where they will "go out and play some sing", and quickly launches into a fiery thirty-two measure solo from Eldgrdige.  In the first sixteen, he leans back on the beat, leaving a short space before launching dramatically into his upper register, but in bars sixteen through twenty four, he play a repeated figure that is derived directly from Hawkins' saxophone style. 


And look what I found on YouTube:
