Currently listening (and enjoying!) the Dragon LP DRLP137 that is supposed to have the November 23, 1959 
 
 
 
but it's Bobby Timmons on piano, not Walter Davis! 
 
Checked with the Lee Morgan Discography  that was included in the Lee Morgan book 'Delightfulee' by Jeffery McMillan. 
The discography correctly identifies the LP as coming from the December 1960 concert in Stockholm
