I have a US issue Genesis "Foxtrot" with Side 1 on both sides, while labels are correct. What is really odd, and why I didn't notice it when I bought it, is that sides have different mastering with different length of dead wax.
I also have a MoFi Beatles "Help!" that was left somewhere in hot environment and it all sort of melted and warped, so only a few tracks are playable nearer the hole, and with a lot of wow...
