Hi, pesch! I always like to meet people who like The Beatles enough to read the good books about them. Depending on your definition of expensive, it’s not really too awful expensive to get all of their records on CD, except for some oddities which are unavailable commercially. You would only need the EMI CD box, Singles box, EPs box, Live At The BBC and its two CD singles, the Free As A Bird and Real Love CD singles, 1, Yellow Submarine Songtrack, Let It Be…Naked, and the two Capitol Albums sets. Then it starts getting expensive. To get the whole experience, you need the first four UK albums in stereo, plus Sgt. Pepper and The White Album in mono, but these are not commercially available on CD.
There are quite a few remixes that have only been issued on vinyl, and some early stereo cuts only available on CD on the '62-'66 set, so you need to get 1962-1966 and 1967-1970, Live At The Hollywood Bowl, Love Songs, Rock And Roll Music, 20 Greatest Hits and (US) Rarities.
And then it gets even more expensive, with imports from the Netherlands and Germany and France and Spain and Russia and Japan and China and Australia and Mexico and Argentina…each of these countries has compilation albums not available in any other country. And, of course, there are colored vinyl limited editions, picture discs in 7" and 12", promotional records, picture sleeves, label variations, you name it! But there’s more! There are in the neighborhood of 3000 Beatles bootlegs that contain nearly everything they ever recorded that isn’t on an official album… concerts, radio & TV broadcasts, interviews, demo versions, acetates of different mixes, intact series of outtakes and alternate mixes. It’s incredible what’s out there. But it’s really fascinating. I have around 500, collected over 30 years.
The 27-minute “Helter Skelter” has never been available. It is the most sought-after Beatles recording, but only Abbey Road and Paul McCartney have copies. They don’t seem to be willing to part with what’s on them.
