Jane and Chris talk to leading Beatles expert Mark Lewisohn at his archive about the Beatles introduction to copyright and the ways in which they changed the music industry in the 1960s. Mark (https://www.marklewisohn.net/) is the author of multiple best selling books on the Beatles, the most recent of which is 2013's Tune In, the first volume in the three part definitive history of the band. Mark generously gave us the benefit of his time and expertise and guided us through some of the copyright infringement cases associated with the Beatles' music as well as their approach to parody requests. This is part 1 of two podcasts. Part 2 features a tour of Mark's archive and more on his research process and his relationship with libraries and archives.
