The camera pans across the turntable several times while record "2" is playing. The location of the tone arm on the record is inconsistent, with the arm being at random locations on the record face rather than being at the perimeter in early shots and closer to the center in later shots.
In one shot, the camera pans from the turntable to the speaker, then pans from the speaker to the turntable a few seconds later. Rather than take a new shot, they simply reversed the original pan shot. As a result, the record is turning in the wrong direction when the turntable comes back into view.
