St. Michael The Archangel Prayer made into a song. Other info about the prayer per Marty Barrack.

ST.MICHAEL THE ARCHANGEL

Saint Michael the Archangel,
defend us in battle.
Be our protection against the wickedness and snares of the devil.
May God rebuke him, we humbly pray;
and do Thou, O Prince of the Heavenly Host - by the Divine Power of God -
cast into hell, satan and all the evil spirits, who roam throughout the world seeking the ruin of souls. Amen. Most Sacred Heart of Jesus, Have Mercy on us (3X)

Martin K. Barrack - Second Exodus book

"Christ warned His faithful that the twentieth century would be extraordinary. In 1884, Pope Leo XIII experienced a terrifying vision. Consulting with several Cardinals after the Holy Sacrafice of the Mass in his private Vatican Chapel, the Pope paused at the foot of the altar. Suddenly, he bacame pale and catonic. After a short interval, however, he resumed normal behavior and said, "Oh, what a horrible picture I was permitted to see!" The Pope told his Cardinals that he had seen demons and heard satan's guttural voice boasting to God that he could destroy the Church and drag the world to hell if her were given sufficient time and power. satan had asked God for a century of enhanced influence, and it was granted. The Pope further understood that if satan didn't destroy the Church during the twentieth century, he would suffer a crushing defeat. The Pope hurried to his office and wrote this (above) prayer."
