"Jesus Wants Me for a Sunbeam" is a song originally recorded by Scottish alternative band The Vaselines for their EP Dying for It. It is a parody on the Christian children's hymn, "I'll Be a Sunbeam," which has the opening line "Jesus wants me for a sunbeam." The Church of Jesus Christ of Latter-day Saints, otherwise known as the Mormons, have a children's primary program which includes Sunbeams (a class for 3-year olds). The theme song to this class is, "Jesus Wants Me For a Sunbeam."
The song was a hit only in indie-pop and twee circles until in 1992, The Vaselines re-released the song with a slight title change ("Jesus Doesn't Want Me for a Sunbeam") on the compilation album "The Way of the Vaselines: A Complete History."
Nirvana released a cover titled "Jesus Doesn't Want Me for a Sunbeam" on their live acoustic album "MTV Unplugged in New York." Two more versions of this song were released on the 2004 box set With the Lights Out. This included an acoustic version recorded in Europe in 1994, along with a live electric performance on the DVD section of the box-set.
On the version contained on the MTV Unplugged in New York album, Kurt Cobain refers to the song as: "a rendition of an old Christian song, I think. But we do it the Vaselines' way." 
Elvis Costello uses the line "Maybe Jesus wants you for a sunbeam" in the song "Alibi" from his 2002 album When I Was Cruel.
