I agree, that is the most horrible aspect. In my case I have lost more friends to distance than death. But the death of my first wife and parents--awful for me.

Not too many Mingus collaborators are still with us! Also born on this day, saxophonists C Sharpe (1931), Kidd Jordan (1937), and Kaoru Abe (1949), as well as pianist Stanley Cowell (1941) and drummer John Preininger (1947).
