The words to this old gospel song were penned by Johnson Oatman, Jr. (1856-1922), who wrote the lyrics for around 5,000 hymns and gospel songs. Oatman pastored a small congregation in New Jersey while making his living in the retail and insurance industries. The melody to The Hallelujah Side was composed by J. Howard Entwisle (1866-1901).
Here are two arrangements of the melody for guitar and mandolin. Each arrangement features the basic melody followed by a break that stays close to the original.
