I recently bought the stereo remasters 2009 box. They're the only Beatles CDs I've ever owned. I mentioned the box to one of my (older) friends, who told me I had to get the mono box as well. So I was researching the mono box, and saw that Help! and Rubber Soul include the "original 1965 stereo mixes" in addition to the mono mixes. According to Wikipedia these original stereo mixes were replaced by updated stereo mixes in 1986 by George Martin for the first CD releases because he wasn't happy with the original 60s stereo mixes. Is that the full story? I mean, he was happy with all the previous stereo 60s mixes, but not those two in the middle of the discography? I know the albums were originally released in mono, and I've read that stereo was an afterthought. But still, if the previous albums' stereo mixes were all fine, what happened with these two albums? And when were all the other stereo mixes prepared that were used for the 2009 stereo box? Aside from the last three albums which were released in stereo from the start, were the rest the afterthought 60s stereo mixes? Or prepared at some other point?
