Bob Schinske leading 539 Supplication, from the 1991 Denson edition of The Sacred Harp, at the 2018 Pacific Northwest Convention — Washington (a.k.a. the Seattle Convention).
This is another one of those Sacred Harp songs that is rarely led, yet is worth singing. My first impression is positive: good melody, solid bass and treble parts, and the composer must have liked altos (or maybe was married to one) because the alto part is definitely above average. I’ll going to have to sing this one through a few times, and see if it grows on me.
