"Yellow Submarine" mixes

On May 26, 1966, The Beatles started work on a new John/Paul song for Ringo entitled "Yellow Submarine". This tune would prove quite popular as it was pulled from the LP and issued as a single along with "Eleanor Rigby" and a number one all over the world.
The basic tracks featured acoustic guitar, bass, drums, tambourine and Ringo's lead vocal. An overdub of all four Beatles singing along was also added at the session.
Fast forward to June 01 1966 and the effects were added to the song including John blowing bubbles, bells being clanged,a noisemaker, party chatter, etc. An edit piece was also added at the session with the sound of marching feet and a "rap" style chatter from Ringo. The edit piece was not used on the original LP nor was it used on the original single in the 60s but was commercially released on the Apple single 45/CD "Real Love" as a bonus track.
The mono mix has the acoustic guitar on the first strum but the stereo mix has the acoustic guitar entering the sound picture on the second strum. The stereo mix for some reason omits a backing line from John in the third verse with his "life of ease" response vocals. The mono has the effects throughout the song yet the stereo mix for some reason fades them out temporarily.
The "real love" mix has the effects turned up all the way through the song and includes the spoken intro while the commercial  Apple LP/CD "Yellow Submarine Songtrack" which synchs up take four with take five. The intro is not present on this one, but the effects are nicely heard and mixed evenly and spread over the stereo spectrum.
Here's an example of take 5 with the lead vocal, backing vocals and effects overdub.
