"Some time ago we recorded the Polish version of the song "40:1" with several friends from Polish bands. It was an exciting experience, and then we decided to give the rights to this song to the Great Orchestra of Christmas Charity, which will soon release it officially."
Mullback: "We've been thinking about it (recording the Polish version - ed. note) for some time, but we didn't have a chance before. It's interesting to listen to Joakim singing in Polish. We will have help from invited guests. Among other musicians, we'll have help from Hate and Vader."
Pär: "Oh yes it was a real challenge - I could sum up in a nutshell. Although our vocalist Joakim speaks a little Czech, thanks to this he understands Polish slightly, but in general Polish turned out to be a completely new language for us..."
- Sabaton planned to record "40:1" in Polish at least since July 2008.
- The band planned to release 40:1 single somwhere in 2008/2009, judging by the The Art of War frame present on the single cover.
- The single was cancelled because Joakim was unable sing the whole song in Polish.
- The Polish flag on the unreleased single cover is incorrect. The single cover used flag with coat of arms, which is only used as ensign by the Polish Navy. Using this flag, one is actually informing that is a ship of the Polish Navy, thus the use of the flag is wrong.
