The Lennon-McCartney years of 1966 through 1970 marked the most fruitful songwriting collaboration in the history of rock music, certainly, and maybe in the history of all popular music, period! And this 112-minute documentary proceeds to make that case by getting you inside their creative process, with contributions by friends Klaus Voorman, Barry Miles and Maureen Cleaves, musicians Alan Moore and Chris Ingham, journalists Robert Christgau and Anthony De Curtis, authors Johnny Rogan, Pete Doggett, Steve Turner and Nigel Williamson, and more, buttressed by rare footage and classic performances. Fascinating and in-depth!
