On December 15, 1966, finishing touches were made on the four rhythm tracks that were recorded the previous session. Although Chandler enjoyed working at CBS and he appreciated the high quality of the recordings they made there, he ended his professional connection with the studio after a disagreement between him and owner Jake Levy over his failure to make payment. Chandler had planned to pay Levy for the sessions after the album was completed, but Levy demanded payment upfront. Chandler viewed this as an unreasonable expectation, and he vowed that he would never again do business with CBS. The fifth and final song recorded there was "Red House". As stereophonic sound was not yet popular among music fans, these recordings were all monaural mixes; Ross explained: "back then ... mono was "king". All the effort went into the mono." He estimated that they spent no more than 30 minutes mixing any one track.
