Witches gather at black masses. Bodies burning in red ashes. On the hill the church in ruins.?

Question

Is the scene of evil doings.

What is it called and who sang it?

Answer 1

Black Sabbath's War Pigs. Sung by Ozzy Osbourne.

Answer 2

That's Ozzy's version, Just Ozzy, not Sabbath. Black Sabbath's is much better. I don't know whay Ozzy lamed it out so much when he sang it all by himself? So it's War Pigs by Ozzy Osbourne.
