My (returning) guest is Andrew Grant Jackson, author of the newly-published 1973: Rock at the Crossroads. He makes the case for this period being a time of tremendous conflict: AM vs FM - 60s giants vs emerging upstarts - mainstream vs underground, all achieving levels of success whether at the time or in years later as influences. Against this backdrop, the four ex-Beatles issued five all albums of new material in total; all of which made the Top Ten (while three scored US number one hit singles, two of them back-to-back). We discuss where The Beatles as a collective and individually fit into the picture and how this year set the table for arguably greater triumphs in the year that followed.
