Art Blakey would not have wound up poverty stricken, if he had quit hitting on "Nica". He didn't realize she was a 'Baroness' or didn't know what that meant. Rich Americans pay a fortune to get a title like that by marrying someone with a title. She was trying to help manage his affairs, and he was hitting on the lady. She could take a bath with nothing but a cigarette in her cigarette holder, listening to Monk and Miles, or whoever happened to be jamming downstairs, and no one would dare take a peek. She went to the worst neighborhoods in New York ( so bad that cops wouldn't even go to them), and let the winos guard her Bentley while she took in the set at a reserved table.
It would seem that would have told Blakey something; but no, not until the lady got tired of trying to help him, and I don't think he realized even then what went down; but I was told that drummers aren't the brightest bulbs.
Enjoy the music.
