I was at Mike Caro's Substudio, (his home studio), in Staten Island, doing session work for months with Mike Appel, when Mike introduced me to a female singer/friend, (Patch).
Patch mentioned she loved The Beatles, so, with that, I started to play Some Beatle songs on the Roland console piano out in the main room. She mentioned the song, Yesterday. Not sure if it was that night or later, I played my arrangement of Yesterday, with Mike Caro recording it by using a long cord. We had always tracked my keyboard which would be in the control room. Patch and Caro asked me to produce the cover. So, after I was happy with the piano arrangement, I asked Caro to record Patch's vocal while he also recorded my piano. I wanted that live, ebb and flow feel, (in the moment). Patch stood right next to me and watched me play as she sang the lead. She would be aware of my arm and hand movements as to the feel of it all. She was amazing at how quickly she picked up on it all, as we didn't rehearse it. We both knew the song of course, so I wanted a fresh capture for it.
She then added harmony back at the usual mic area, (center of the room), allowing natural room reverb to be part of the vocals, as Caro always would do for any vocal.
I added a string arrangement in one take, not trying anything beforehand. (Head arrangement, which I seem to do better than hashing over things). I then wanted Caro to play acoustic guitar, which he thought to use his classical guitar. We were excited when he was tracking that, for if you ever get the chance to witness Caro record anything, you'll understand. I suggested where to play, for which he took over and did what he felt, which is what you do with him. He, being ill, labored over getting it all just so, which I already thought he did great before he said, "Nah,,,,AGAIN"! When he smiled at the end of the song, we all knew it was perfect. Caro mixed it, BUT I ;ater Mastered it without knowing what I was doing. Caro might have the best version. The one you will hear is my overdoing things in the attempt to Master. (I should have stuck to doing things I know).
With the over compressed and other issues in mind, (excuse me for that), here is my take on the tempo and feel for an original female version on a great Paul song, Yesterday.https://soundclick.com/share.cfm?id=12060036
