George Nelson Allen (September 7, 1812 – December 9, 1877) was an American composer and geologist who was associated with Oberlin College, where he taught for 34 years.
 He is primarily known today for writing the melody to the hymn Precious Lord, Take My Hand.

("Give Me That") "Old-Time Religion" (and similar spellings) is a traditional Gospel song dating from 1873, when it was included in a list of Jubilee songs—or earlier.
 It has become a standard in many Protestant hymnals, though it says nothing about Jesus or the gospel, and covered by many artists.
 Some scholars, such as Forrest Mason McCann, have asserted the possibility of an earlier stage of evolution of the song, in that "the tune may go back to English folk origins" (later dying out in the white repertoire but staying alive in the work songs of African Americans).
 In any event, it was by way of Charles Davis Tillman that the song had incalculable influence on the confluence of black spiritual and white gospel song traditions in forming the genre now known as southern gospel.
 Tillman was largely responsible for publishing the song into the repertoire of white audiences.
 It was first heard sung by African-Americans and written down by Tillman when he attended a camp meeting in Lexington, South Carolina in 1889.
Gospel music is a genre of Christian music.
 The creation, performance, significance, and even the definition of gospel music varies according to culture and social context.
 Gospel music is composed and performed for many purposes, including aesthetic pleasure, religious or ceremonial purposes, and as an entertainment product for the marketplace.
 Gospel music usually has dominant vocals (often with strong use of harmony) with Christian lyrics.
 Gospel music can be traced to the early 17th century, with roots in the black oral tradition.
 Hymns and sacred songs were often repeated in a call and response fashion.
 Most of the churches relied on hand clapping and foot stomping as rhythmic accompaniment.
 Most of the singing was done a cappella.
 The first published use of the term "gospel song" probably appeared in 1874.
 The original gospel songs were written and composed by authors such as George F. Root, Philip Bliss, Charles H. Gabriel, William Howard Doane, and Fanny Crosby.
 Gospel music publishing houses emerged.
 The advent of radio in the 1920s greatly increased the audience for gospel music.
 Following World War II, gospel music moved into major auditoriums, and gospel music concerts became quite elaborate.
Precious Lord is the 16th studio album by Al Green and his third gospel album, released in 1982.
"Take My Hand, Precious Lord" (a.k.a. "Precious Lord, Take My Hand") is a gospel song.
 The lyrics were written by the Rev. Thomas A. Dorsey (1899–1993), who also adapted the melody.
"Kid" Prince Moore was an American blues musician, from the United States, who recorded 17 songs from 1936 to 1938.
 Moore played in a Piedmont blues style, similar to that of Blind Blake.
 Moore also recorded two Gospel Music tracks, "Church Bells" and "Sign of Judgement".
 Moore also accompanied blues pianist Shorty Bob Parker on six of his own tracks.
 Bruce Bastin, in his book ""Red River Blues: The Blues Tradition in the Southeast"", suggests that Moore may have originated from The Carolinas, but as of 2017 there is no documented knowledge of Moore's life.
Thomas Andrew Dorsey (July 1, 1899 – January 23, 1993) was known as "the father of black gospel music" and was at one time so closely associated with the field that songs written in the new style were sometimes known as "dorseys".
 Earlier in his life he was a leading blues pianist known as Georgia Tom.
"You'll Need Somebody on Your Bond" (later titled "You're Gonna Need Somebody on Your Bond") is a gospel song that is attributed to both tradition and to gospel blues musician Blind Willie Johnson.

 Over the years, several other musicians have recorded renditions of the song.
