I think with the Beatles, you had to be there to experience it.
For me it's very much 'meh', but I was born the day they had one of their last number ones.
A lot of my friends in their late 70s it was the sound track of their teenage years. They go mental when it comes on at discos (or weddings).
Together with the Stones, Cliff Richard, Elvis, and a lots of other artists they were unique and sowed the seeds of modern pop.
