All episodes of SATB all feature conversations. Sometimes they are with Beatles authorities: writers or academics who’ve done the research and come up with a thesis. Others are with folks in the business: musicians who were inspired by The Beatles and who’ve walked the walk – written songs, recorded records, gone on tour. They know the ins and outs of Beatles music.

Then there are the Beatle witnesses: folks who knew the individual Beatles well, either by direct family relations (Mike McCartney, Jenny Boyd), working directly for The Beatles (Kevin Harrington, Chris O’Dell, Ken Mansfield, Chris Thomas, Alan Parsons, John Leckie, Tony King, and so forth) or else spending considerable time in their world (journalist Ray Connolly, photographer Ethan Russell, journalist Ivor Davis, photographer Tom Murray, filmmaker Paul Saltzman, Nancy Lee Andrews, May Pang, and so forth). These people come to SATB to share their insights and observations, bringing us that much closer to the world The Beatles created.
