The first task was to add some home made tape loops, some guitar and other effects onto the existing take 3 of "Tomorrow Never Knows" in order to fill up some tracks by looping the tapes over and over in various areas of the studio.
The second task was to record a new song written mainly by Paul entitled "Got To Get You Into My Life" which was inspired (according to Paul) by his habit of smoking pot and his love for the weed.
Here we have take 5 of the song - an early version - including an acoustic guitar, some drums by Ringo and a studio organ played by (it's been said) George Martin. Some vocals are also added: Paul sings the main line while both George Harrison and John Lennon add to the backing vocals.
This version of the song can be found on some of the "Alternate Revolver" bootlegs and is available commercially on the Apple 3-LP/2-CD "Anthology 2". I've included a link to the tune:
