For most listeners, the Edwin Hawkins Singers recorded the definitive version of "Oh Happy Day." I can't argue with that. The vocals are joyful, resonant, and suffused with spirit. That version has been and always will be one of my go-to Easter Sunday tracks.
If you prefer a jazzier version, however, Quincy Jones approached it compellingly. The flute carries the melody with appropriate vocal punctuation, and the rhythm section, especially the bass, is prominent. It's still a reverential version--but funked up and a tad softer.
