I stand corrected! I had this confused for the Train Wreck session, definitely do not have a copy.

That'll be a fun trip!     

This  interesting information is from Robin Kelley's book on Thelonious Monk. "Thelonious  even kept his music at Nica's, usually in a briefcase next to the piano. Fire was his main concern; he never worried about theft. That is, until he heard Jackie McLean's LP, "A Fickle Sonance", released later in the year. One of the cuts on the album, "Five Will Get You Ten", was credited to Sonny Clark, the pianist on the date. The song was actually one of Monk's compositions, "Two Timer". He had written it at Nica's but had not recorded it. Monk may have shared the lead sheet with Clark;l he may have even played it for him. But Clark was a frequent visitor to the "Cat House", and he even lived there off and on. His herion habit was out of control, and like most other junkies he resorted to stealing for a fix. Neither McLean nor any of the other sidemen suspected that the song had been stolen. To my knowledge, Thelonious never confronted Clark about it nor mentioned it to anyone. He just let it go."
