This graphic compares the Beatles main activities from the years of 1963 to 1964. There are parallels in timing between each year, but the similarities between '64 and '65 are particularly notable.
" was a curious year for the Beatles, one in which they consolidated all the successes and excesses of 1964 by virtually repeating everything already achieved. They made a second feature-film, Help!, they toured North America...and Britain again...John even had a second book published."
