This is based on a live recording which is the (Official Audio) for the medley in the original key of G to Ab.  This is a simple lead sheet with vocal cues and three-part choir (SAT).  But also there is a SATB choir part for full choirs.  (Note: there is no SATB in the sample Score) This is a great tool for teaching the choir parts.  This is from Aretha Franklin’s recording “Amazing Grace” recorded in 1972 with James Cleveland and the Southern California Community Choir.  Ask about other keys.
