Mike Curb Congregation has been played on NTS shows including Donna Leake, with Agnus Dei first played on 31 March 2020.

Starting as a student at Grant High School in California's San Fernando Valley in the late 1950s, Curb began performing with his own bands and formed a vocal group, the Mike Curb Congregation. In later years, the group achieved worldwide success with many albums including "Burning Bridges," "Put Your Hand in the Hand," and "Softly Whispering I Love You." The Congregation also was seen on national television every week on the Glen Campbell variety show on CBS, and recorded No. 1 hit records including "The Candy Man" with Sammy Davis Jr. and "All for the Love of Sunshine" with Hank Williams Jr., the singer's first No. 1 single, which also was co-written by Curb.
