On the beach, Bruce and Grace grab matching, blue towels draped on the tops of their lounge chairs, which have nothing else there, and Grace sits down on the chair farthest from Charles. Then, in a very long shot, Bruce is leaving, but a red and white fabric is now draped over Grace's chairback. Subsequently, in the medium shot, Grace is now on the chair adjacent to Charles.
Disputing comment here on audio/visual sync: The keyboardist's hands are in sync with the electric piano part. The electric piano plays an arpeggio leading into a held chord.
Inside the Blue Note Club, the flautist's hands are visible as she is holding a F, yet her fingers are moving between fingerings for a B and the right hand's usage on Ds. Also, the pianist or keyboardist's hands are moving, but it does not match any of the music.
