There are some records from the mid to late 1960s (maybe earlier too) that were recorded with extremely split stereo. In the case of The Beatles, the early stereo recordings were done this way in order to produce a better mono master. There are some stereo recordings of this type that just don't sound good on the radio, or they need some extra help in order to come out ok. I believe that at least some of them were recorded out-of-phase. The best example which I've heard many times sounding bad on radio is "Purple Haze" by The Jimi Hendrix Experience.
At the end of 2012, I did a yearly radio show commemorating artists who passed away in 2012. One of them was Joe South. I played "Walk A Mile In My Shoes". I had both a CD copy and my original 45 rpm record. I deferred to the CD, which was a mistake. On-air, the vocal was almost completely missing. I quickly cued up the vinyl '45' to the next instrumental bridge, and dumped out of the CD and into the vinyl version, which sounded ok. When I got home, I played the '45' and noticed that the lead vocal is on one channel. I also recall that when I played the '45' back when it was new, I heard some musical sounds that I just didn't pick up when listening to it on, back then, AM radio.
