Allan Kozinn was a music critic and culture reporter for the New York Times from 1977 to 2014, where he wrote principally about classical music. In that capacity, he interviewed Paul McCartney several times, and saw him perform in a great variety of configurations and venues—from singing with a hand mic at the Lonestar Roadhouse, playing rock oldies at the Cavern, in Liverpool, and performing in small halls like the Ed Sullivan Theater and the Highline Ballroom, to full-scale concerts at Madison Square Garden and Yankee Stadium. He currently contributes regularly to the Wall Street Journal, the Washington Post and other publications. He has taught courses at the Juilliard School and New York University (including a course on the Beatles at the latter), and has written seven books, among them The Beatles—From the Cavern to the Rooftop (1995), Got That Something! How The Beatles’ ‘I Want to Hold Your Hand’ Changed Everything (2013), The New York Times Essential Guide—Classical Music (2004).

The principal researcher for the McCartney Legacy series, Adrian Sinclair studied film at the University of Wales, Aberystwyth, and served a traineeship with ITV in Yorkshire, England, where he learned his craft as a documentary film editor. He’s worked for almost every major broadcaster in the world, including the BBC, ITV, Sky, Channel 4, National Geographic, Discovery and MTV. As well as receiving recognition for his work from the Royal Television Society in England, Adrian’s 2010 documentary Stealing Shakespeare (BBC/Smithsonian) was Emmy shortlisted for Best Documentary.
