Johnjec's confusion confirms the stupidity (or should that be 'greed') of not having each LP available on 2-CD mono/stereo sets, with the relevant A/B/EP/BBC/'Anthology' sides as extras.....see 'The Kinks'.
As you're getting the mono (mono being the definitive versions) box, it's really only 'Yellow Submarine' (with the George Martin orchestration on Side 2 - not the 'song-track' edition), 'Abbey Road' and 'Let It Be' (not 'Let It Be...... Naked') that you'll need, together with the essential 'Live at the BBC' volumes 1 & 2.
Personally, I'm hanging back until Apple do the whole thing properly, which should be in about 2028. See you there!
