"Oh Happy Day" is a 1967 gospel music arrangement of an 18th-century hymn. Recorded by the Edwin Hawkins Singers, it became an international hit in 1969, reaching No. 4 on the US Singles Chart, No. 1 in France, Germany and the Netherlands and No. 2 on both the UK singles chart and Irish Singles Chart. It has since become a gospel music standard.
The recording is notable for the muted piano, drum and bass backing and the dominant use of the left-hand stereo channel which features the performance of lead singer, Dorothy Combs Morrison. The recording was made at Hawkin's church, the Ephesian Church of God in Christ in Berkeley, California.
