This is not an edit, but either a mixing discontinuity or intentional decision. About 55 seconds in listen to the kick drum in the chorus. A bit loud. Next time the chorus comes around at about 2 minutes in, the kick drum is mixed back a bit.
This was in a time when unless the console had automation, a complex mix down could be several people on the faders, each handling a task. Sometimes mixing a section to two track, stopping if they made a mistake or needed to reconfigure the console. Then backing up the multitrack a few seconds, doing it again, and finally splicing the two track to make the final mix. Some engineers had no fear of editing multitrack tape, which could be one inch or two inches wide. Besides the fact they were cutting all the tracks at once, they had to deal with the angle of the cut and the width of the tape causing the edit to not happen at the same time on all the tracks. Some engineers recorded most time sensitive parts on the center tracks to minimize audibility of the edit. Or they did a 90 degree cut...
I realize much of this is performing for the camera and the video is edited. Part two of this is interesting
Here in part two watch a portion of the mix down from multitrack to two track at a 9:50. At about 10:15 you see Neil Kernon making the fade out with his right hand on the master while his left hand is on tracks. At 10:10 to 10:16 John Oates is reaching in and slighty raising vocal tracks on the tail end of the mix, as it fades, and they finish at about 10:30. Neil is a wise producer and does not object when one of the artists reaches in. And John Oates was correct, he did something that is was done frequently and sounded good on the radio.
Btw that is an AKG mic. My boss and I installed one of those at an AM R&B station in the late '70s or early '80s. Very crisp and present sound.
This is a better link to Weekend in New England. AnotherProf has the mono 45. I remember hearing this on AM and noticing it.
