War Pigs is the first track off of Black Sabbath's second studio album Paranoid.
The song's outro is entitled "Luke's Wall" on the US edition.
"War Pigs" was originally titled "Walpurgis", dealing with a black mass which was based on the Dennis Wheatley novel "The Devil Rides Out" where a group of friends battled Satanists at a black mass on Walpurgis Night which Geezer Butler had read.
The original version was only recorded once on John Peel's radio show in 1970. According to some sources the band and the record company were concerned with the recent events of the Manson killings. Not wishing to be seen as Satanists or dark occultists in anyway, Geezer chose to rewrite the song into an anti-war statement.
The original version of the song can be found on Ozzy Osbourne's compilation album "The Ozzman Cometh" from that same session.
Ward's first memory of playing "War Pigs" live was at The Beat Club in 1968 where the band had to preform multiple gigs and they didn't have enough music written to fill the set, so they play long jam sessions. "War Pigs" was made from one of those sessions.
Generals gathered in their masses
Just like witches at black masses
Evil minds that plot destruction
Sorcerers of death’s construction
In the fields the bodies burning
As the war machine keeps turning
Death and hatred to mankind
poisoning their brainwashed minds
Oh Lord yeah
Politicians hide themselves away
They only started the war
Why should they go out to fight
They leave that all to the poor
Time will tell on their power minds
Making war just for fun
Treating people just like pawns in chess
Wait ’till their judgment day comes
Now in darkness world stops turning
As the war machine keeps burning
No more war pigs have the power
Hand of God has struck the hour
Day of judgment God is calling
On their knees, the war pigs crawling
Begging mercy for their sins
Satan laughing spreads his wings
Oh Lord yeah
