1964 was the year the Beatles took over the world.    However, the foundations for that were laid in 1963.    The Beatles visited Sweden and planned trips to France, Australia, New Zealand and the United States before anyone knew for certain there was gold to be found.    This week we tune in to a documentary covering their June 1964 visit to New Zealand, from its origins in the summer of 1963 to the run of shows and their eventual return to the UK.
