A return to kentrivia

Wherein did you ever notice? No? Me neither.

1. Nixon, 1968? Didn’t really think so.
   
2. A.A. Milne
   
3. Ethiopa
   
4. Plaque? No.
   
5. Having my demon spawn child, what a wonderful way to say you were brainwashed by the devil-worshipping neighbors.
   
6. Aries. Took me much longer to figure this out than it should have.
   
7. I own none of these albums, so any answer would require research. Research most likely to be pointless. So my guess is "blue."

Three correct: 2, 3, 6.
