Jesus Saves, also known by the titles "Jesus Can't Play Rugby" or "Jesus Can't Go Hashing" is a popular drinking song common among Hash House Harriers and rugby union players. As with any rugby song, it is tongue-in-cheek and is consciously offensive. It is sung at socials among teams of many nations at nearly every level of competition.
Sung to the tune of Battle Hymn of the Republic (aka "John Brown's Body").
