Something I saw earlier if you scroll up, you'll see someone mentioning the credits mentioned on LZ 4 for When the Levee Breaks according to what he sees on his "CD" version. Quite frankly, right off the top of my head, I'm not abolutely certain as to the accuracy of this particular example. BUT.......

I will say this much. If you do some research and look for the ORIGINAL VINYL RECORDS from the time periods when they were released (ie; first pressings), and compare them to what today's "CD's" show as far as copyright credits, I'm absolutely certain that you will see at least one or more differences on a number of their albums. This in itself should be evidence that over the years, they've surely had to answer for the discrepancies in their credits.

Always consider the source!!!!!...........
