All right, well - midway through June so here's an update on the two completely unidentified tracks so far:
Track 3 - Not particularly enjoyed by many here. Unique singer who self produced much of his output via his income as a dentist.
Track 9 - This one seems to be one of the more popular tracks among this selection. Incorrect guesses so far on who the pianist is include: Ahmad Jamal, Ramsey Lewis, Errol Garner, Billy Strayhorn, Hampton Hawes, Chick Corea, & Eldar Djangirov. Drummer guessed as Roy Haynes and that is incorrect as well. The drummer has a connection to Haynes however.
