At 77 and having listened to jazz since 1957 I'm probably of your father's generation and may have had similar experiences. On the albums I listen to - they range from Jack Teagarden to Eric Alexander - I've usually heard at least one of the artists in person. For example, on your Blue Note 1540 album I've seen Mobley, Morgan and Silver, but not Byrd, Chambers and Persip. And all this on this side of the Atlantic!
