Anthology 3 OOPSed

I have tried OOPS on tracks on Anthology 2, here are the results!
Many songs sound just like a simple combination of stereo channels, while others are completely remixed. The greatest surprise was the mono tracks: there is always some remaining sound after OOPS in all of them.

Everything was done digitally. I played the CDs on my CD-ROM drive, recorded samples of selected parts of each song at 22 KHz, 16-bit using Cool Editor 1.53, then applied the Cool's filter "Channel Mixer" ("Vocal Cut" preset).

Glossary

Reduced or Background: a sound similar to the original, trebly and at low volume. This is the result of OOPSing a sound that is heard close to the center in stereo, but not exactly centered.
Mono Mix: result of the simple combination of both stereo channels into one.
Remix: after OOPS, all sounds (or most of them) can be heard, but at different levels, compared to a Mono Mix.

Notes on Mono Tracks

No mono track on A2 gives a blank signal after OOPS. Some of them seem to be unbalanced, others are mono tapes played on stereo machines, and some of them seem to have reverb added, as mock stereo!

If the mono sound is not perfectly centered (unbalanced), there will be some difference between the channels and the result will be a reduced original sound.
If the mono tape was played on a stereo machine, the signal is splitted incorrectly between the stereo tracks, and may also "move" slightly around the center. After OOPS, the result is similar to the unbalanced, but if the sound "moves", the volume of OOPS sound changes.
Finally, on some tracks a reverbed sound is heard after OOPS. This means: the mono recording had reverb added in stereo during the preparation of Anthology 2 masters. This happens on many studio outtakes.

The Tracks

A Beginning

Remix, with some instruments heard "distant" (for instance the flute).

Happiness Is A Warm Gun [MONO]

Original sound reduced and reverbed (sounds as you were outside the room!).

Helter Skelter [MONO]

Reduced original sound.

Mean Mr.Mustard
Polythene Pam
Glass Onion

John's Esher demos have the stereo channels completely separated (there's nothing in the center) so OOPS gives mono mixes.

Junk

Sounds like a low volume mono mix with little reverb.

Piggies [MONO]

Reduced original sound, distorted and oscillating.

Honey Pie

Similar to John's demos.

Don't Pass Me By

Organ, bass, sleigh bells and some of the drums. Vocal and the rest of the drums reduced.

Ob-La-Di, Ob-La-Da

Percussion and saxes are emphasized, and all the rest sounds reverbed, as they were playing inside a large room (and you're hearing from outside).

Good Night

Most of the track is mono so OOPS gives the original sound reduced and reverbed, and isolates the orchestra (that appears in stereo).

Cry Baby Cry

Drums, bass and slide guitar. John's vocal and guitar appear at low volume and distorted.

Blackbird

Almost a mono mix, but Paul's voice appear "distant".

Sexy Sadie

"Karaoke-mix", with John's voice distant.

While My Guitar Gently Weeps

Reverb and echoes, initially at low volume and louder to the end.

A Day In The Life

Part 1 (main) [MONO]: Reduced original sounds, oscillating.
Part 2 (orchestral crescendo): Remix very similar to Mono Mix.

Good Morning Good Morning

Vocals and guitars, plus reduced drums. The bass is missing.

Remix ommiting the tabla (percussion), which is barely heard in background. The other instruments are "distant" and tamboura (drone-strings) has a bit of phasing.

Sgt. Pepper's Lonely Hearts Club Band (Reprise) [MONO]

Reduced original sound, plus vocal and snare drum echos.

You Know My Name (Look Up The Number)

Part 1: Vocals and claps
Part 2: Vocals reverbed
Part 3: Vocals and crowd noises
Part 4: Second vocal (John?) is always heard. First vocal (Paul?) begins in background, reverbed, then comes up suddenly on "You know my name, look up the number" (4:02), after then it oscillates between low volume reverbed and full volume. In stereo, it begins centered and comes to the left suddenly at that point - a mixing mistake?
Part 5: Paul (?) humming "Hoooya-Hooya'know" and "Oh you know my name..." towards the end.
All parts (except part 4) have rhythm track in background.

I Am The Walrus

Remix with vocal and drums in background.

The Fool On The Hill (Demo) [MONO]
