"Denomination Blues" is a gospel blues song composed by Washington Phillips (1880–1954), and recorded by him (vocals and zither) in 1927. In 1972, Ry Cooder revived this almost-forgotten song on his album Into the Purple Valley.In 1938, Sister Rosetta Tharpe (1915–73) recorded a gospel version of the song (vocals and guitar) under the title "That's All". She subsequently recorded several versions with orchestral accompaniment.
