Cover art for Bak Et Halleluja lyrics by Kaizers Orchestra

All the Kaizers Orchestra song meanings (and translations) you could ever need are right here under the [English] sections: http://www.freewebs.com/kaizersinst/lyrics.htm

The album is not in chronological order, but it roughly follows one storyline. Marcello Conradas is the sailor in the songs Dekk Bord, Bøn fra Helvete, and Ompa til du Dør. The Mafia, run by Mr. Kaizer, often meets in Marcello’s cellar for drinks, music, and Russian roulette.

Bak et Halleluja is about Dominique, whose job was to protect Tony Fusciante. Tony decided to play Russian roulette (in Rullett) and died. Now, Dominique is in trouble and pleads to the mafia priest Father Martin to help him. Martin tells Dominique to find a double for Tony, run away, and start a new life. Though, in the end, Father Martin still tells Monsieur Clavier for the irresistible reward.

170 and Bris do not follow this storyline. They just describe two military stories. Perhaps those are related to the characters in the cellar, it’s not clear.
