The Beatles gold mine ran out of salable ore long ago. So all they can do is to sell slag to the tourists.
Even though I'm a hardcore Beatles fan, I never bought the last remastered box-set release. I might do that one day, though, when the price of used copies finally comes down on eBay. Gives me something to look forward to.
Even with my tin ears, there was a LOT of music in the mono recordings that I had never "noticed" before. Highly recommended.
