"Because" Session

The backing track for the John Lennon composition "Because" consisted of 23 takes with sparse instrumentation. Take 16 was used for the commercial recording. John played his electric guitar along with a Baldwin harpsichord played at the same time by producer George Martin and bass added by Paul. Although you can't hear it, Ringo was tapping his high hats to keep time while the song was being played.
There were two vocal sessions for the tune: one was on August 01 and the other on August 04 1969 with John, Paul and George sharing harmonies. This vocal arrangement was written by George Martin who deserves the credit. The song was recorded at EMI Studio 2 in London.
Bootlegs of the vocal only harmonies are available with such examples as the vinyl "Unsurpassed Masters, Volume 5 & 6" and the CD "Not Guilty" among others. The problem is that there is leakage from the headphones you can still slightly hear the instrumental backing being played. The commercial release of the vocal only version can be heard on the Apple/EMI 3LP/2CD "Anthology 3" as well as a version on the Apple/Universal "Love" soundtrack. The difference between the bootlegs and the commercial versions is that the leakage of the instrumental backing is lessened on the commercial versions using using studio faders in between the vocal sentences to bring the sound down.
The moog sythesizer solo was added from Room 43 (George Harrison's moog brought from his home was used - the same one used on his "Electronic Sound" solo Zapple LP) as an overdub on August 05 1969. The solo was played by George Harrison as well. Finally, "Because" was mixed in stereo only on August 12 1969 and included for the upcoming LP at the time.
