Sunday Best producer Margo Precht Speciale is also the granddaughter of legendary TV host Ed Sullivan.
Bo Diddley is shown performing, but what is not mentioned is that Ed Sullivan told him to play Tennessee Ernie Ford's song "16 Tons", which was a big hit at the time. He thought "Why should I play someone else's song?" and at the last minute switched and played his signature tune "Bo Diddley" instead. Sullivan was livid over the switch and permanently banned Bo Diddley from appearing again.
The Executive Producers of the documentary Sunday Best are Kerry Gordy and Margo Precht Speciale. Kerry Gordy is the primary Executive Producer for the Netflix documentary, which Sacha Jenkins directed.
