Within me I know is contained in one of one hundred fourteen folders for "Jump for joy" consisting of 1 two page piano conductor score in C Major concert, and 1 two page piano conductor score in A Major concert -- in pencil -- in identified hand (Whaley).
Piano conductor scores do not indicate instrumentation. Score in C Major appears incomplete. Score in A Major is noted on the verso of the score in C Major. -- from the Duke Ellington Library.
