I should probably re-watch
sometime.
Both 
for the slinks to click. I’m sure I’ve heard that recording of “Compared to What” before, and starting around 0:26 in that recording and going on for ~10 seconds or so it sounds like Les McCann is quoting or borrowing a phrase from “Aquarius” (“When the moon is in the seventh house / And Jupiter aligns with Mars”). That’s something I really like about listening to jazz: musicians pulling bits and pieces from other sources into their improvisation to give it an unexpected flavor. I feel like it’s kind of a reward for paying attention, listening not only to the song at hand but also to other things and having awareness of diverse influences.
That kind of thing seems like a very human choice, too. It’s not one person regurgitating something he or she heard once: It’s an artist infusing his or her work with something that came before and including it with a personal touch.
Suck on that, AI!
