Clara Ward (1961)
Mahalia Jackson (live) (the call-and-responses really make this)
Mahalia Jackson (live, 1964) (the sound dynamics she shows off here are jaw-dropping)
Itty bitty Natalie Cole (I think she's in her mid-twenties? here). If you only know her from "Pink Cadillac" you are in for a surprise. UTU comment says Natalie Cole was taking part in "In The Spirit" with Rev James Cleveland, Marion Williams, Dorothy Norwood and The Southern California Community Choir at All Saint's Church, Northampton, England on Thursday 27th November 1980.
