Black Sabbath - Paranoid - 1970
The album was originally titled War Pigs, but allegedly the record company changed it to Paranoid, fearing backlash from supporters of the ongoing Vietnam War.
At the time, the band felt that the song was lighter, with the potential to become a single.
The album cover features a man in red with a sword. Ozzy Osbourne states in 'I Am Ozzy' that the name change had nothing to do with the Vietnam war and was entirely due to the record company deciding the album would be easier to sell if it was named after the single, which had already had significant success by the time the album was released, reaching number 4 on the UK Singles Chart.
