Teddy pushes Billy and Daisy to connect by sharing a microphone during recording. However, at the end, Billy isolates Daisy's vocals to listen only to her singing, which he would not be able to do since they were sharing the same microphone.
In the recording studio in 1974, Billy and Teddy talk in a closet with shelves full of tapes. One of the tapes is an Ampex 456 in a box with a design that was not used until the mid-1980s.
