Paranoid isn't the best Sabbath song in my opinion War Pigs destroys it. I guess Sabbath would be my second choice though.
I have to disagree with you there. And if not Paranoid, then maybe Fairies Wear Boots or Mob Rules or Am I Going Insane.
Yes, you are right. From B to C, I evolved somewhat, in going from a very small number of songs to a larger set. OK, never too late. Let's add these in now:
The Band, The Weight (I did not know that they are Canadian);
Beatles, Don't Bother Me;
Blue Oyster Cult, Don't Fear the Reaper;
Boston, More than a Feeling;
Byrds, Turn.
