The string arrangement reinforces the track's air of disappointment while in the groaning cello line that connects The 2 halves with the bridge, notably the "blue" seventh in the next bridge move (the Eplayed after the vocal line "I do not know / she would not say") and inside the descending run by the viola that segues the bridge again in the verses, mimicked by McCartney's vocal on the next pass in the bridge.
So there is certainly leakage there. Then I stated I'd do a string quartet. The musicians objected to twiddling with headphones, so I gave them Paul's voice and guitar on two speakers both aspect of their microphones. So you can more info find leakage of Paul's guitar and voice to the string tracks.
Jack is aware if he can don't forget the words to many of the Beatles tunes, he would turn into a popular rock-star. The only just one he can't try to remember would be the "Eleanor Rigby". He reconstructs many in their songs from his memory.
