Here, There and Everywhere Update

In my November 19th. post, I discussed the song Here, There and Everywhere and how I thought John sang lead while on the album they listed Paul as lead.  How could they "tweak" John's voice to sound more like Paul's?  I found the answer in George Martin's book, With A Little Help From My Friends  The Making of Sgt. Pepper (1994, with William Pearson).

Martin describes how he changed the recording tape speed of When I'm Sixty Four, Lovely Rita, and Lucy In The Sky With Diamonds.  It's my speculation that this was done to make the voice of the man who replaced Paul sound more like Paul's.  For Lucy In The Sky With Diamonds, Martin says:
     "The vocals on 'Lucy" weren't recorded at normal speed.  The first was recorded at a frequency forty-five cycles, our normal recording frequency being fifty cycles.  In other words, we slowed the tape down, so that when we played it back the voice sounded ten per cent higher:  back in the correct key, but thinner-sounding . . . ."

And how about Here, There and Everywhere?  I found an entry in Mark Lewisohn's book, The Complete Beatles Chronicles, (1988, 1992) where Lewisohn talks about further work that was done on the recording on Thursday June 16, 1966:
     "A 14th take was created by reduction onto which Paul superimposed his lead vocal, slowed down on the tape to sound speeded up on playback."  Paul wouldn't have needed his own voice speeded up to sound like himself, but a speed-up of JOHN's voice would sound more like Paul's.

The mystery is why John was substituted for Paul on the track and why they listed the lead as Paul.  Part of the continuing mystery.
