Short answers, pulled from the story.
The Capitol Albums, Volume 2 was officially released on the 11th of April 2006. Capitol chose that date because it marked the 42nd anniversary of the Beatles holding a record 14 positions on the Billboard Hot 100 chart at once, one week after the group had also monopolized the chart's top five positions.
The Capitol Albums, Volume 2 includes all 92 tracks from the Beatles' 1965 American Capitol Records releases, each presented in both a stereo mix and a mono mix. All of the tracks on The Early Beatles and many of the tracks on Beatles VI appeared in stereo on compact disc for the first time in this set.
Some early copies of The Capitol Albums, Volume 2, those released before the 11th of April 2006, contain fold-down mono mixes of Beatles VI and Rubber Soul instead of the original 1965 mono mixes. Beatles author Bruce Spizer explained that a third party mastering facility mistakenly sent stereo-to-mono mixdowns to be pressed rather than the vintage mono mixes.
Capitol A&R executive Dave Dexter Jr. mastered The Capitol Albums, Volume 2, using sub-master tapes he pulled from Capitol's vaults in 1965. Dexter added reverb to several tracks and created simulated stereo versions of songs that had originally existed only in mono.
The Capitol Albums, Volume 2 debuted on the Billboard 200 album chart on the 29th of April 2006 at number 46, with approximate sales of 27,000 copies. The RIAA certified it gold on the 19th of May 2006.
A copy of The Capitol Albums, Volume 2 with the correct mono mixes runs slightly longer than one with the mispressed fold-down versions. Disc two, Beatles VI, runs 56 minutes 16 seconds correctly versus 56 minutes 1 second when mispressed, and disc four, Rubber Soul, runs 59 minutes 8 seconds correctly versus 59 minutes 1 second when mispressed.
